  • Synthesis and properties of graphene oxide-boron-modified phenolic resin
    • Authors: Yi, X; Feng, A, Shao, W, Xiao, Z.
      Pages: 505 - 517
      Abstract: Boron–modified phenolic resin (BPR) has a good thermal property, but it has deficiencies in mechanical performance. To obtain PR materials with good thermal property, graphene oxide (GO) was added along with BPR to form a GO–boron-modified PR (GO-BPR). In this study, BPR and GO-BPR were prepared and their thermal resistance and mechanical properties were investigated. In addition, the effects of GO content on the thermal resistance of GO-BPR were studied. Results demonstrate that the optimal GO content was 0.5%. The thermal properties of GO-BPR with 0.5% GO improved 1.06 times when compared with that of BPR, and the peak degradation temperature of GO-BPR increased by approximately 10°C. When compared with BPR composite, the bending, tensile, and impact strengths of the GO-BPR composite materials with 0.5% GO-BPR increased by 46, 38, and 53%, respectively.

  • Novel photoactive poly(aryl ether)s containing bisazobenzene pendants for
           optical storage
    • Authors: Zhang, J; Zhang, H, Zhang, Q, Jiang, Z, Chen, Q, Zhang, Y.
      Pages: 518 - 524
      Abstract: A series of novel poly(aryl ether)s containing bisazobenzene moieties (bisazo-PAEs) have been synthesized based on a new bisazobenzene monomer, 4-(4-(4-nitrophenyl)diazenylphenyl)diazenylphenyl)-2,6-difluorobenzenesulfonate. Their chemical structures and properties were characterized by means of infrared, proton nuclear magnetic resonance, and ultraviolet–visible spectroscopies. These polymers show good thermal stability with glass transition temperatures above 160°C. the bisazo-PAEs show significant photoisomerization effect after irradiation with 405 nm light. By exposing the bisazo-PAEs films to an interference pattern of laser beams at modest intensity, significant surface-relief gratings can be formed.

  • Effects of functionalized graphene nanoplatelets on the morphology and
           properties of epoxy resins
    • Authors: Wang, F; Drzal, L. T, Qin, Y, Huang, Z.
      Pages: 525 - 536
      Abstract: Graphene nanoplatelets (GnPs) were successfully functionalized with a liquid rubber, amine-terminated poly(butadiene-co-acrylonitrile) (ATBN), and the functionalized GnPs (ATBN-GnP) were characterized by microscopic and spectroscopic techniques. Different amounts of ATBN-GnP and pristine GnP were individually incorporated into an epoxy resin to fabricate epoxy composites. Compared with the pristine GnP, ATBN-GnP demonstrated stronger ameliorating effects due to an enhanced GnP-epoxy interfacial adhesion. At 5.0 wt% GnP content, the flexural modulus of GnP/epoxy composite increased by 18.1%, whereas the ATBN-GnP improved the flexural modulus by 22.1% at the same fraction. A remarkable enhancement of quasi-static fracture toughness was obtained at 5.0 wt% GnP and 5.0 wt% ATBN-GnP with 76.2% and 92.8% increase, respectively. Incorporation of 5.0 wt% ATBN-GnP improved thermal conductivity of the neat epoxy by 133.6%, and the thermal conductivity of 5.0 wt% ATBN-GnP/epoxy is about 16% higher than that of the pristine GnP/epoxy. The superior reinforcement of ATBN-GnP is attributed to the strong interfacial bonding between ATBN-GnP and epoxy matrix as confirmed by microscopic observations.

  • Preparation and magnetic and thermal properties of flexible polyimide
           films with iron nitrophthalocyanine-coated magnetite microspheres
    • Authors: Liu, C; Qu, C, Wang, D, Yu, W, Xiao, W, Su, K.
      Pages: 537 - 546
      Abstract: To effectively utilize the one-step solvent–thermal route to prepare iron (Fe)–nitrophthalocyanine/magnetite (Fe3O4) hybrid microspheres, we have developed a novel series of flexible Fe3O4/Fe-phthalocyanine (FePc)/polyimide (PI) composite films with various Fe3O4/FePc nanoparticle loadings (15, 27, and 40 wt%) and imidized at different temperatures (200°C and 300°C). The morphology and structure of the composite films were monitored using scanning electron microscopy, Fourier transform infrared spectroscopy, and X-ray diffraction, and the hybrid microspheres were found uniformly dispersed in the polymer matrices without any agglomeration. Mechanical and thermal properties of the composites were also investigated. The observed results indicated enhanced thermal stabilities, dramatically increased tensile modulus, and increased glass transition temperatures of the composite films, with the increment in the content of inorganic nanoparticles. Besides that, the Fe3O4/FePc/PI magnetic films showed higher saturation magnetization (24.33 emu g–1, 27 wt% Fe3O4/FePc loading) with high-temperature treatment compared with that of the Fe3O4/PI film (18.79 emu g–1, 27 wt% Fe3O4 loading). It proved to be an effective way to prevent Fe3O4 nanoparticles from oxidizing by coating the nanoparticles with organic layer. The flexible composite films can easily be moved under a relatively low magnetic field, indicating them to be the high-performance absorbing materials in potential applications.

  • Synthesis and characterization of optically active polyimides and their
           octa(aminophenyl)silsesquioxane nanocomposites
    • Authors: Sadhasivam, B; Muthusamy, S.
      Pages: 547 - 561
      Abstract: New optically active diamine (3,5-diaminophenyl)((R)-3,4-dihydro-1-phenylisoquinoline-2(1H)-yl)methanone was successfully prepared. Optically active polyimides (PIs) were synthesized by reacting the prepared diamine with the aromatic tetracarboxylic dianhydrides, namely, 3,3',4,4'-benzophenone tetracarboxylic dianhydride/pyromelltic dianhydride by thermal imidization method and characterized using Fourier transform infrared and nuclear magnetic resonance spectral techniques. Additionally, PI nanocomposites were also prepared by incorporating amino-functionalized polyhedral oligomeric silsesquioxane named as octa(aminophenyl)silsesquioxane (OAPS). The cut-off wavelengths of PIs and their nanocomposites were found to be less than 350 nm, indicating that the PIs are transparent. The PIs and their nanocomposites were found to have glass transition temperature between 204°C and 269°C (differential scanning calorimetric analysis). The 10% weight loss temperature and char yield were found to be 319.5–420.3°C and 26.3–62.7%, respectively. The PIs were found to be amorphous as indicated by X-ray analysis. The scanning electron microscopic images of the nanocomposites also reveal uniform distribution of the nanoparticles in the nanocomposite. PIs and PI/OAPS nanocomposites were found to have low dielectric constant in the range of 2.59–3.36.

  • Synthesis and properties of cross-linkable poly(arylene ether nitrile)s
           containing side propenyl groups
    • Authors: Shen, S; Pu, Z, Zheng, P, Liu, X, Jia, K.
      Pages: 562 - 569
      Abstract: Cross-linkable poly(arylene ether nitrile)s containing side propenyl groups (DPEN) were synthesized through nucleophilic aromatic substitution polymerization from biphenol, 2,2'-diallylbisphenol A (DBA), and 2,6-dichlorobenzonitrile. The structures of resultant copolymers were characterized by Fourier transform infrared and proton nuclear magnetic resonance spectroscopies. The properties of copolymers were investigated by thermal (differential scanning calorimetry and thermogravimetric analysis) analysis, inherent viscosity measurements, and mechanical tests. The results showed that allyl groups rearranged into propenyl groups during the polymerization. The copolymers with increasing content of DBA had high glass transition temperatures ranging from 207°C to 169°C and good thermal and thermo-oxidative stability with the 5 wt% loss temperatures in the range of 511–423°C under nitrogen and 471–402°C in air atmospheres, respectively. They also exhibited good mechanical property with tensile strength of 105–79 MPa. Meanwhile, the cross-linking reaction was studied through heat treatment. The result showed that the properties of DPEN containing side propenyl groups changed obviously after heat treatment, due to the fact that the double bond of PEN can be readily cross-linked to form net-shape polymers at high temperature.

  • Influence of chemically and plasma-functionalized carbon nanotubes on
           high-performance polymeric nanocomposites
    • Authors: Ajeesh, G; Bhowmik, S, Venugopal, S, Varshney, L, Baluch, A, Park, Y, Gilsang, S, Kim, C. G.
      Pages: 570 - 580
      Abstract: This investigation highlights different surface functionalization processes of multi-walled carbon nanotubes (MWCNTs) and their effects on mechanical properties of polyetherimide nanocomposite. Surfaces of MWCNTs were modified by chemical process and by low-pressure plasma process. There is a significant change in physicochemical characteristics of MWCNTs after chemical and low plasma treatment evident from scanning electron microscopy, transmission electron microscopy, and X-ray photoelectron spectroscopy studies. Due to surface modification of CNTs, there is a significant change in surface morphology and increase in oxygen functionalities such as C=O, C–O, and COOH especially evident in low-pressure plasma treatment; however, differential scanning calorimeter and thermogravimetric analysis studies reveal that thermal properties of the composite do not alter as such. There is a significant increase in mechanical properties of high-performance polymeric nanocomposites when surface-functionalized MWCNTs are dispersed in polymeric matrix; however, surface characteristics of the composite remain almost unchanged evident from contact angle and surface energy studies.

  • Curing behaviors and performance of a carboxyl-terminated butadiene
           acrylonitrile rubber/bisphthalonitrile resin system
    • Authors: Pan, H; Xu, M, Lei, X, Jia, K, Liu, X.
      Pages: 581 - 590
      Abstract: The curing behaviors and processability of 2,2-bis[4-(3,4-dicyanophenoxy)phenyl] propane (BAPh) and carboxyl-terminated butadiene acrylonitrile rubber (CTBN) were investigated using differential scanning calorimetry and dynamic rheological analysis. The results indicated that the introduction of CTBN significantly catalyzed the polymerization of the CTBN/BAPh system and that the processability of the CTBN/BAPh prepolymer could be controlled by temperature, processing time, and CTBN content. CTBN/BAPh/glass fiber (GF) composite laminates were prepared in this study. In terms of mechanical and dielectric properties, the CTBN/BAPh/GF composite laminate with 10 wt% CTBN content showed an outstanding flexural strength and modulus of 534 MPa and 32 GPa, respectively, as well as higher dielectric constant and lower dielectric loss compared with the BAPh/GF composite laminate. The results on thermal property showed that the CTBN/BAPh/GF composite laminate with 10 wt% CTBN could withstand a high decomposition temperature of 580°C under nitrogen and 520°C in air atmospheres. Hence, this work proposes an approach to improving the processability of phthalonitrile resin so as to further widen its industrial applications.

  • Novel bismaleimide/diallylbisphenol A resin modified with multifunctional
           thiol containing isocyanuric ring and long-chain aliphatic unit
    • Authors: Ohtsuka, K; Kimura, H, Ikeshita, S, Nakao, H, Tsubota, S.
      Pages: 591 - 599
      Abstract: 4,4'-Diphenylmethane bismaleimide (BMI)/2,2'-diallylbisphenol A (DABPA) resin was modified with a multifunctional thiol containing isocyanuric ring and long-chain aliphatic unit (tris[(3-mercaptopropionyloxy)-ethyl]-isocyanurate (TEMPIC)). To investigate the relationship of the curing reaction and properties of cured BMI/DABPA resin modified with TEMPIC, the temporal change in the functional groups during the curing reaction process was analyzed using Fourier transform infrared analysis. Despite the decreased cross-link density with increasing TEMPIC concentration, the glass transition temperature of BMI/DABPA resin was not decreased by modification with TEMPIC. The storage modulus of BMI/DABPA/TEMPIC resin maintained a value on the order of 109 Pa in the rubber region, which is similar to that of the unmodified resin. The fracture toughness and flexural strength were also improved by modification with TEMPIC. Moreover, the observation of the fracture surface of BMI/DABPA/TEMPIC resin using scanning electron microscopy showed a uniform structure with no phase separation. These results were consistent with the single α-relaxation peak in the loss tangent curve of the dynamic viscoelastic behavior.

  • Synthesis and thermal properties of high-temperature phthalonitrile
           polymers based on 1,3,5-triazines
    • Authors: Sheng, H; Zhao, F, Yu, X, Naito, K, Qu, X, Zhang, Q.
      Pages: 600 - 609
      Abstract: Two kinds of phthalonitrile monomers based on 1,3,5-triazine structure have been synthesized. The chemical structures of the phthalonitrile monomers were characterized by Fourier transform infrared and nuclear magnetic resonance spectroscopies. Differential scanning calorimetric analysis revealed the curing behavior of the monomers. Thermogravimetric analysis suggested outstanding thermal stabilities of the triazine-structured phthalonitrile polymers. Thermal decomposition kinetic analysis indicated that the activation energy of the two phthalonitrile polymers is 205.6 and 152.3 kJ mol–1, respectively. Dynamic mechanical analysis showed that the storage moduli (E') are 3.62 GPa and 3.66 GPa, respectively, and glass transition temperatures of both the monomers are higher than 350°C. Postcuring effects were investigated, which showed that more excellent thermal and mechanical properties were achieved with postcuring.

      Abstract: A series of organic–inorganic hybrid resin systems are prepared using hydroepoxy, 1,3-bis(aminomethyl)cyclohexane, and epoxy-functionalized polyhedral oligomeric silsesquioxane (POSS-Ep). The thermomechanical properties and shape-memory behaviors of the hybrid materials are systematically investigated by differential scanning calorimetry, thermogravimetric analysis (TGA), dynamic mechanical analysis, bend test, and shape recovery test. Results indicate that the glass transition temperature (T g) and rubber modulus gradually increase as the POSS-Ep content increases. The thermal stabilities of the hybrid materials gradually increase with increasing POSS-Ep content. The bend strength of the hybrid materials increases firstly and then decreases as POSS-Ep content increases, showing an extreme value for the hybrid materials with 3.17 mol% POSS-Ep content. Finally, investigation of the shape-memory behavior of the hybrid materials reveals that full recovery can be observed after only several minutes when the temperature is equal to or above T g. The shape recovery time decreases at first and then increases as POSS-Ep content increases at T g, T g + 10°C, and T g + 20°C. These results are attributed to the increase in POSS-Ep content.

      Abstract: Polyphenylene sulfide (PPS)/clay composites were prepared by simple melt blending. Three different kinds of surfactants such as cetyltrimethyl ammonium bromide (CTAB), sodium dodecyl benzene sulfonate (SDBS), and synthetic 1,3-dihexadecyl-3H-benzimidazolium bromide (Bz) were used as organic modifiers for the organic modification process. The benzimidazolium-modified montmorillonite (Bz-MMT) and CTAB-modified MMT (CTAB-MMT) exhibited larger interlayer spacing than SDBS-modified MMT (SDBS-MMT), while SDBS-MMT and Bz-MMT exhibited higher thermal stability compared with the CTAB-MMT. The morphology of the PPS/organic MMT nanocomposites was evaluated by X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. The nanocomposites based on SDBS-MMT and Bz-MMT exhibited good overall dispersion of organic MMT with a mixed dispersion of intercalated and exfoliated structures. Differential scanning calorimetry and thermogravimetric analysis (TGA) were used to evaluate the thermal properties of PPS/organic MMT nanocomposites. The crystallization process of PPS in all nanocomposites was accelerated, and the crystallinity also increased, when compared with the pure PPS from the DSC analysis. The TGA analysis indicated that nanocomposites based on SDBS-MMT and Bz-MMT exhibited higher thermal stability than composites based on CTAB-MMT due to the well-dispersed nanoplatelets.
