  • Physical properties of TEMPO-oxidized bacterial cellulose nanofibers on
           the skin surface
    • Authors: Seung-Hyun Jun; Seol-Hoon Lee; Seoyeon Kim; Sun-Gyoo Park; Cheon-Koo Lee; Nae-Kyu Kang
      Pages: 5267 - 5274
      Abstract: Water-dispersed bacterial cellulose nanofibers were prepared via an oxidation reaction using 2,2,6,6-tetramethyl-1-piperidine-N-oxy radical (TEMPO) as a catalyst. It was found that TEMPO-oxidized bacterial cellulose nanofibers (TOCNs) synthesized via sodium bromide-free methods are similar to those synthesized using sodium bromide. The TOCNs retained their unique structure in water as well as in emulsion. TOCNs adhere to the skin surface while maintaining nanofibrous structures, providing inherent functions of bacterial cellulose, such as high tensile strength, high water-holding capacity, and blockage of harmful substances. When gelatin gels as model skin were coated with TOCNs, the hardness representing the elasticity was increased by 20% compared to untreated gelatin gel because TOCNs could tightly hold the gelatin structure. When porcine skin was treated with TOCNs, carboxymethyl cellulose, and hydroxyethyl cellulose, the initial water contact angles were 26.5°, 76.5°, and 64.1°, respectively. The contact angle of TOCNs dramatically decreased over time as water penetrated the fibrous structure of the TOCN film. When observed by scanning electron microscopy and confocal microscopy, TOCNs on the skin surface provided physical gaps between particles and the skin, blocking the adsorption of particulate matter to the skin surface. On the contrary, the structure of water-soluble polymers was disrupted by an external environment, such as water, so that particulate matter directly attached to the skin surface. Characterization of TOCNs on the skin surface offered insight into the function of nanofibers on the skin, which is important for their applications with respect to the skin and biomedical research.

  • Preparation of highly flexible cellulose acetate membranes modified by
           hyperbranched poly(amine ester)-epoxidized soybean oil and evaluation of
           its filtration properties
    • Authors: Hossein Mahdavi; Aliasghar Kamyabi; Taieb Shahalizade; Hossein Asadollahi Taheri
      Pages: 5389 - 5402
      Abstract: Cellulose acetate (CA) is considered as one of the first materials used in membrane technology. However, CA membranes suffered finding their way for widespread commercial applications due to low mechanical stability and sensitivity to bio-fouling. In this study a green procedure was developed to overcome some of CA drawbacks in membrane applications. For this purpose 2nd generation of hyperbranched poly(amine ester) (HBPAE-G2), was synthesized using methyl 3-[bis(2-hydroxyethyl)amino]propanoate and triethanolamine through a pseudo one-pot polycondensation, reacted with soybean oil fatty acid, and then double bonds epoxidized by H2O2/formic acid to acquire hyperbranched poly(amine ester)-epoxidized soybean oil (HBPAE-ESBOFA). Finally, this reactive additive was blended with CA membrane dope solution to obtain simultaneously plasticized and cross-linked structure. Synthesis procedures were monitored by FTIR and NMR techniques, and membrane samples were investigated using ATR-FTIR, FE-SEM (top and cross-sectional), TGA and DSC. Filtration properties were studied by determining pure water flux, water contact angle, bio-fouling, water content, mean pore size and solute rejection tests. Permeability tests showed decline in water flux, but fouling resistance, salt rejection and thermal properties improved. Moreover, modified samples showed fascinating flexibility and mechanical stability enhanced dramatically.

  • Reversing the structural chirality of cellulosic nanomaterials
    • Authors: Kevin M. Conley; Louis Godbout; M. A. Whitehead; Theo G. M. van de Ven
      Pages: 5455 - 5462
      Abstract: Nature organizes cellulose, a linear polysaccharide of D-glucose and an important component of plants and trees, into intricate structures with twists in the trunks of trees, microfibrils within cell walls, and at the nanoscale. Manipulating the hierarchical organization of materials requires control down to the molecular level. In computational models cellulose nanocrystals twist, and Quantum Mechanical models have shown recently that chains at the surface of nanocrystals are right-handed, while the interior chains are mostly left-handed. Here we provide experimental evidence showing the induced circular dichroism of two optical dyes reverses when adsorbed onto thin cellulose nanocrystals. The reversal in optical activity is consistent with earlier TD-DFT B3LYP 6-31G calculations of the induced optical activity of Congo red adsorbed onto twisted 1 0 0 crystal surfaces of cellulose and demonstrates control of the chiral molecular interactions at the nanocrystal surface. The results suggest it may be possible to reverse the structural twist handedness of the nanocrystal itself and build chirality-dependent hierarchical supramolecular structures from cellulose.

  • Effect of the graft density of cellulose diacetate-modified layered
           perovskite nanosheets on mechanical properties of the transparent
           organic–inorganic hybrids bearing covalent bonds at the interface
    • Authors: Satoru Sato; Kenji Shintani; Naokazu Idota; Takashi Nishino; Yoshiyuki Sugahara
      Pages: 5463 - 5473
      Abstract: Transparent organic–inorganic hybrids with a whitish colour were prepared from cellulose diacetate (CDA) nanosheets derived from Dion–Jacobson-type ion-exchangeable layered perovskite HLaNb2O7·xH2O (HLaNb) to prepare CDA-based hybrids bearing covalent bonds between HLaNb nanosheets and CDA matrices for improved mechanical properties. An n-decoxy derivative of HLaNb (C10_HLaNb) was exfoliated in acetonitrile by ultrasonication. TEM and AFM images revealed that C10_HLaNb was exfoliated into individual nanosheets. In order to explore the local environment around HLaNb nanosheets, a very small amount of CDA was reacted with a C10_HLaNb nanosheet dispersion [molar ratio COH:(NbOH + NbOC10H21) = 4:1] at 80 °C, and solid-state 13C NMR with cross polarization and magic angle spinning techniques showed that an alcohol-exchange-type reaction was proceeded to graft the CDA chains to the HLaNb nanosheets via new Nb–O–C covalent linkages. The CDA-based hybrids were prepared by dispersing 5 mass% of HLaNb nanosheets in CDA and subsequent heating at 80 °C for 1–7 days to cause a grafting reaction, and the product prepared by a 1-day grafting reaction exhibited improved mechanical properties compared to neat CDA; the Young’s modulus, tensile strength and toughness increased by 18, 34 and 78%, respectively. The mechanical properties deteriorated with further extension of the reaction period, however. In addition, a hybrid film prepared by mixing CDA and a C10_HLaNb nanosheet dispersion exhibited only a slight improvement in mechanical properties. These results clearly indicate that formation of an appropriate number of Nb–O–C bonds at the nanosheet/CDA interfaces is effective for improving mechanical properties.

  • Effect of micro/nano white bamboo fibrils on physical characteristics of
           epoxy resin reinforced composites
    • Authors: Cuong Manh Vu; Le Hoang Sinh; Hyoung Jin Choi; Tien Duc Pham
      Pages: 5475 - 5486
      Abstract: As a green filler comprising both nano- and micro-sized fibrils, micro/nano white bamboo fibrils (MWBFs) were treated with a silane coupling agent (S-MWBFs) prior to their introduction in an epoxy resin (EP). The sequential processes of steam explosion, alkaline treatment, and micro grinding were used to prepare to MWBFs. The effects of the S-MWBFs on various characteristics of the cured EP such as compatibility, fracture toughness, morphology, mechanical property, and flame retardation were studied. The fracture toughness and mechanical characteristics of both the storage modulus and tanδ maximum increased following addition of the S-MWBFs to the EP. Notably, the fracture toughness of the EP with 0.3 wt% of S-MWBFs was 22.2% higher than that of unmodified resin. Scanning electron microscopy presented somewhat rougher surfaces with shear deformation and tortuously twisting cracks, resulting in a higher fracture toughness in S-MWBF-modified epoxy samples. However, fire testing showed that the presence of S-MWBFs increased the burning rate of the EP.

  • Thermodynamic effect on interaction between crystalline phases in
           size-controlled ACC-bacterial nanocellulose and poly(vinyl alcohol)
    • Authors: Gento Ishikawa; Tetsuo Kondo
      Pages: 5495 - 5503
      Abstract: The aqueous counter collision (ACC) method can provide single bacterial nanocellulose ribbons (ACC-BNC) in a desired width, from a pellicle produced by Gluconacetobacter xylinus. Kose et al. (Biomacromolecules, 12:716–720, 2011) reported that the ACC process transformed the major Iα crystalline phase of the native fiber to a stable Iβ phase, without decreasing the overall crystallinity. The current study investigated the variation of the crystalline phases of ACC-BNC, upon interaction with poly(vinyl alcohol) (PVA). ACC-BNC of desired width was mixed with PVA, without any chemical reaction occurring. This resulted in a homogeneous suspension. The equilibrium melting point of PVA in cast nanocomposite films was investigated, as a probe for evaluating the crystalline surface properties of the ACC-BNC. A decrease in the equilibrium melting point of PVA would have indicated attractive interactions between the PVA and ACC-BNC. However, the nature of the ACC-BNC surface in the presence of PVA depended on the ACC-BNC width. Thicker ACC-BNC acted as a nucleating agent for PVA. Thinner ACC-BNC acted as a diluent of PVA. This tendency was opposite to the case for Iβ-dominant ACC-wood nanocellulose. ACC-BNC acting as a nucleating agent was more efficient than ACC-wood nanocellulose. The results suggested that ACC-BNC surfaces, which probably contained I α phases, had different characteristics to those of Iβ-dominant ACC-wood nanocellulose surfaces.

  • Surface grafting of bamboo fibers with 1,2-epoxy-4-vinylcyclohexane for
           reinforcing unsaturated polyester
    • Authors: Ming-En Fei; Tianshun Xie; Wendi Liu; Han Chen; Renhui Qiu
      Pages: 5505 - 5514
      Abstract: The present study focused on the surface treatment of bamboo fibers (BFs) with a bifunctional monomer, 1,2-epoxy-4-vinylcyclohexane (EVC), in the presence of N, N-dimethylbenzylamine as the catalyst, which results in the grafting of the fibers with C=C bonds on the surface. The modified BFs carrying C=C bonds were used to prepare bamboo fibers reinforced unsaturated polyester (UPE) composites by hand lay-up compression molding. Hence, chemical connections between the modified-fibers and UPE resins were formed via the free-radical polymerization of the C=C bonds during the preparation of the BFs–UPE composites. XPS analysis proved that the EVC was covalently bonded onto BFs. XRD analysis revealed that EVC-grafting did not alter the crystal structure of the fibers, but slightly decreased their crystallinity degrees. SEM images indicated an markedly improved interfacial adhesion between BFs and UPE matrices after fiber modification, which significantly increased the tensile strength, flexural strength, flexural modulus, storage modulus, glass transition temperature, and water resistance of the resulting BFs–UPE composites.

  • Cellulose-chitosan beads crosslinked by dialdehyde cellulose
    • Authors: Ung-Jin Kim; Hyeon Joo Kim; Joon Weon Choi; Satoshi Kimura; Masahisa Wada
      Pages: 5517 - 5528
      Abstract: Crosslinked cellulose-chitosan beads were obtained via dissolution-regeneration of cellulose and chitosan by a LiOH/urea aqueous solution, followed by the crosslinking of chitosan via dialdehyde cellulose (DAC). This crosslinking reaction involved the Schiff base formation between the aldehyde groups of DAC and the amino groups of chitosan and subsequent reduction. DAC was prepared through periodate oxidation of cellulose and solubilization in hot water at 100 °C for 1 h. Four grades of DAC-crosslinked cellulose-chitosan were prepared by controlling the amount of cellulose and chitosan. The DAC-crosslinked cellulose-chitosan showed higher stability in the pH range of 2–9 over a long-term 21-day test. Additionally, the DAC-crosslinked chitosan showed a higher bovine serum albumin adsorption capacity as a result of the increased amino group content due to the crosslinking between DAC and chitosan, which occurred at multiple points in spite of a lower degree in crosslinking.

  • One-step removal of insoluble oily compounds and water-miscible
           contaminants from water by underwater superoleophobic graphene
           oxide-coated cotton
    • Authors: Danning Zhu; Yunfei Xia; Jin Yang; Beibei Chen; Shun Guo; Changsheng Li
      Pages: 5605 - 5614
      Abstract: We prepared a superhydrophilic/underwater superoleophobic graphene oxide (GO)-coated cotton for wastewater purification by a simple approach to overcome the difficulty of simultaneously removing insoluble oily compounds and water-miscible contaminants from water. GO can be attached onto the surface of cotton fibers by means of hydrogen bonds between oxygen-containing groups of GO and cotton, with a mass fraction of 6.9 wt%. Large numbers of oxygen-containing groups, combined with the inherent three-dimensional network structure, lead to a water contact angle of 0° and an underwater oil contact angle of 170° ± 1° on the GO-coated cotton. Various oil-in-water emulsions, dye wastewaters and even mixtures of both can be economically and effectively purified by using GO-coated cotton. Most of oils can be filtered with removal efficiency of over 99% and dyes can be absorbed with removal efficiency of over 97%. Our results show that the GO-coated cotton can be regenerated and maintain this high removal efficiency after 50 separation cycles. We anticipate that underwater superoleophobic GO-coated cotton would be an ideal wastewater purification material for practical applications.

      Abstract: A cellulosic adsorbent (PDA–MCC) was prepared by halogenation of microcrystalline cellulose (MCC) and functionalized with pyridone diacid (PDA) for removing lead and cobalt ions from aqueous solutions. PDA–MCC was characterized by Fourier transform infrared spectroscopy, scanning electron microscope, and thermal gravimetric analysis. The performance of PDA–MCC in removing lead and cobalt ions was examined by investigating the adsorption behaviors of lead and cobalt ions on PDA–MCC. Results from the adsorption of lead and cobalt ions on PDA–MCC showed that the adsorption kinetics followed the pseudo-second-order kinetic model, and the adsorption isotherms could be described by the Langmuir model. The maximum adsorption capacities of PDA–MCC towards lead and cobalt ions were determined to be 177.75 and 122.70 mg/g, respectively, which are greater than those of most reported cellulosic adsorbents. The reusable experiment showed that PDA–MCC could be regenerated in an acid solution, and had the adsorption capacities remained greater than 75% even after five cycles of regeneration.

      Abstract: In this work, an efficient and hydrophobic bamboo pulp cellulose-graft-sodium silicate–polyacrylamide (BPC-g-Si–PAM) flocculant was designed and synthesized to improve its flocculation performance as well as the dewatering efficiency of coagulation sludge. The optimal synthesis process of BPC-g-Si–PAM and its optimal flocculation conditions on wastewater treatment were investigated in detail. Compared with unmodified BPC-g-PAM and commercial PAM, hydrophobic BPC-g-Si–PAM flocculant exhibited better flocculation performance with SV30 of 5.8%. Moreover, TSS, COD and turbidity reduction for machining wastewater reached upto 98.1, 86.8 and 97.6%, respectively. Compared with commercial PAM, removal rate increased by 2.69, 7.68 and 2.68%, respectively. And also BPC-g-Si–PAM exhibited higher removal efficiency for ammonia nitrogen (77.7%), total iron (99.3%), total phosphorus (93.6%) and total zinc (96.7%) than PAM. All the results demonstrated that hydrophobic BPC-g-Si–PAM has a potential application prospect in industrial wastewater treatment.

  • Temperature-induced formation of cellulose nanofiber film with remarkably
           high gas separation performance
    • Authors: Xiong-Fei Zhang; Yi Feng; Chaobo Huang; Yichang Pan; Jianfeng Yao
      Pages: 5649 - 5656
      Abstract: Free-standing cellulose nanofiber (CNF) films were prepared by a specially designed oven-drying approach. For the first time, the evaporation rate was carefully controlled to enhance the gas separation performance of the CNF film with the highest H2/N2 and H2/O2 selectivities of 159.4 and 218.2, respectively. The dense structure formed by the CNFs and the intra- and inter-fibrillar hydrogen bonds are believed to contribute to the separation property. Particularly, the specific role of floating-shape film precursor formed at the rapid evaporation stage (stage I) and the mechanism for film formation were investigated. This study demonstrated that the evaporation rate controlled by the heating temperature exhibited significant influence on surface, uniformity and gas separation of the CNF films.

  • Desizing of starch sized cotton fabrics with atmospheric pressure plasma
    • Authors: Carrie Cornelius; Marian McCord; Mohamed Bourham; Peter Hauser
      Pages: 5685 - 5695
      Abstract: Atmospheric pressure plasma is examined as a desizing agent for starch-sized cotton samples. Plasma treatment is examined both for its physical etching properties and for its ability to induce desizing of the starch during a scouring bath. The effect of the plasma gas composition and plasma exposure duration are evaluated. A 2-min helium/oxygen plasma is found to be the only condition that appears to improve desizing of starch.

  • Preparation and characterization of magnetic Fe 3 O 4 –chitosan
           nanoparticles for cellulase immobilization
    • Authors: Yan Lin; Xi Liu; Zhaohui Xing; Yong Geng; Jeffrey Wilson; Deyi Wu; Hainan Kong
      Abstract: Cellulase immobilization is an important issue for cellulose hydrolysis in bioethanol production. In this study, Fe3O4 nanoparticles were synthesized using a coprecipitation method and were coated with chitosan. Glutaraldehyde was used as cross-linking reagent for cellulase immobilization. The morphology, structure, and related physical and chemical properties of the supports were studied by X-ray diffraction, a physical property measurement system, Fourier transform infrared spectroscopy, and Transmission electron microscopy. Response surface methodology was used to determine the optimal cellulase loading efficiency (LE) and standard recovery ratio (RR). The verification tests show the immobilized particles had an LE of 99.6% and an RR value of 68.5%. It was found that immobilized cellulase had a wider range of adaptability to hydrolysis pH and temperature when compared with free cellulase. Five hydrolysis experiments demonstrated effective hydrolysis using immobilized cellulase while maintaining on average 80% of the free cellulase’s activity.
