    ABSTRACT: A facile method was explored to reinforce the poly(N-isopropylacrylamide) (PNIPAm)-hectorite nanocomposite hydrogel (NC gel) by heat treatment at temperature above the volume phase transition temperature (VPTT), which enhanced mechanical strength and reduced swelling capacity with denser microporous structure as compared with the non-treated NC gel. This reinforcement effect was increased by increasing treating temperature and/or treating time, which still remained even after swelling, indicating an irreversible structure change in the treated NC gels. Heat treatment became more effective when the NC gel contained higher clay content. The quartz crystal microbalance (QCM) data showed that the interaction between PNIPAm chains and clay platelets became stronger at temperatures higher than the VPTT, causing an increase in the crosslinking density of the treated NC gels. A strong hydrogel was obtained by heat treatment of the aqueous mixture of PNIPAm and hectorite clay for the first time. POLYM. COMPOS., 2014. © 2014 Society of Plastics Engineers

    ABSTRACT: Fiber hybrid polyimide-based (PI-based) composites reinforced with carbon fiber (CF) and poly-p-phenylene benzobisthiazole (PBO) fiber of different volume fractions were fabricated by means of hot press molding technique, and their mechanical properties and tribological behaviors under sea water lubrication were systematically investigated in relation to the synergism of CF and PBO fiber. Results showed that the incorporation of CF or PBO fiber improved the tensile strength, hardness, and wear resistance of PI. More importantly, because of the synergistic enhancement effect between CF and PBO fiber on PI matrix, the combination of 10%CF and 5%PBO fiber reinforced PI-based composite had the best mechanical and tribological properties, showing promising application in ocean environment.

    ABSTRACT: The Fe3O4/poly(lactide-co-glycolide) (PLGA) composites were prepared via a surface grafting technique. Initially, the poly(lactic acid) oligomer was synthesized and surface-grafted to Fe3O4 nanoparticles. Then, the grafted Fe3O4 particles were compounded with PLGA matrix by a simple solution blending method. The grafted Fe3O4 particles presented enhanced compatibility with PLGA matrix and the composites indicated enhanced dynamic mechanical performance. Electrochemical tests showed that the Fe3O4/PLGA composite coating can help improve the impedance of magnesium samples by 100–300%, and the impedance of the metal may be tunable by altering the components ratio of LA/GA within PLGA matrix. The composites may have potential application for magnesium alloy used in degradable medical implants. POLYM. COMPOS., 2014. © 2014 Society of Plastics Engineers

    ABSTRACT: A poly(amino acid)/β-Ca2SiO4(PAA/β-Ca2SiO4) bioactive composite was prepared by in situ melting polymerization. The composition, structure, and morphology were characterized by infrared spectrometry, X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy, and differential scanning calorimeter. The results indicated that the β-Ca2SiO4 particles were uniformly distributed in the PAA matrix and some interaction was found at the interface between PAA and β-Ca2SiO4. The crystallinity of PAA in the composite was found decreasing with the increase of β-Ca2SiO4 content. The bioactivity of the composite was evaluated by soaking the composite in simulated body fluid (SBF) and results showed that the PAA/β-Ca2SiO4 composite (PSC) could induce a dense and continuous layer of apatite after soaking for 1 week. In addition, the PSC was soaked SBF for 2 months, and the weight loss reached 8.77%, showing the composite could be degradable. Collectively, these results suggested that the incorporation of β-Ca2SiO4 produced a biocomposite with enhanced bioactivity and might have potential applications as a bone tissue substitute. POLYM.

    ABSTRACT: Nanocomposites of ethylene vinyl acetate (EVA) containing iron oxide nanoparticles (IONPs) were prepared by open mill-mixing technique. The effect of loading of IONPs in EVA was characterized by Fourier transform infrared (FTIR), X-ray diffraction (XRD), transmission electron micrograph (TEM), and dynamic mechanical analysis (DMA). The FTIR spectra ascertain the intermolecular interaction between the polymer and IONPs. TEM and XRD studies revealed the structurally ordered arrangement of nanoparticles within the polymer matrix. DMA showed an increase in storage modulus and lesser damping characteristics of composite with the increase in loading of nanoparticles, whereas these properties decreased significantly with increase in temperature. The glass transition temperature shifted toward higher temperature with the increase in content of IONPs. Magnetic properties of the nanocomposites were investigated using vibrating sample magnetometer at room temperature. The saturation of magnetization was progressively increased with the increase in content of nanoparticles. The electrical conductivity, dielectric constant, and dielectric loss of the composite were found to be increased with the increase in volume fraction of nanoparticles. The polymer–filler interaction was also determined from the swelling studies. POLYM. COMPOS., 2014. © 2014 Society of Plastics Engineers

    ABSTRACT: Micro- and nano-scale wear behavior of alumina vis-á-vis alumina-carbon nanotube-reinforced hybrid composites has been studied. In comparison to the pristine alumina, the alumina-carbon nanotube hybrid reinforcement resulted in reduced scratch depth and lower frictional coefficient. Addition of carbon nanotube has effectively modified the pristine alumina into a superior wear resistant filler. POLYM. COMPOS., 2014. © 2014 Society of Plastics Engineers

    ABSTRACT: In this study, epoxy-based nanocomposites with low content mechanically exfoliated graphene were successfully prepared via one-step in situ ball milling method. The effect of graphene on mechanical properties of the nanocomposites was investigated. The results showed that samples with loadings less than 0.1% weight of mechanically exfoliated graphene increased by 160% in tensile strength and 65% in Young's modulus. The experimental value of Young's modulus was also compared with the predictions of the well-established Halpin-Tsai model. In addition, the adding of graphene did not decrease the impact strength of epoxy. The microstructural results showed that the as-prepared graphenes were single- and few-layer graphene sheets and preserved perfect structure. Thus enhancements of mechanical properties in the nanocomposites could be ascribed to the strong interfacial interaction between the stiff graphene nanosheets and the epoxy matrix. POLYM.

    ABSTRACT: Elastomeric polyurethane (PU) was mixed with 0, 10, 15, 20, 25, and 30 wt% of graphite to obtain PUE-based composites. The structure of PU/graphite elastomer was characterized by scanning electron microscopy. It was found that the polyurethane elastomer (PUE) molecular chains were intercalated into the graphite layers and evenly distributed in the matrix. When the graphite content was lower it could make full use of its strength with some loss of plasticity; when the graphite content was too high, the friction between graphite and PUE increased and hence it is more difficult for the macromolecular chain reaction. The polymer was more unstable as a whole. Furthermore, the thermal and mechanical properties of the obtained products were investigated in detail. The result showed that the thermal stability of PUE was improved by the introduction of the graphite. The softening temperature of the PUE/graphite containing 10% graphite was 11°C higher than that of pure PUE. At the same time, the hardness, tensile strength, elongation, 300% tensile modulus, tearing strength of PU/graphite elastomer were also investigated. POLYM.

    ABSTRACT: In this study, the effects of reactive and non-reactive poly(hedral oligomeric silsesquoxane) (POSS) type and their loading level on the mechanical, morphological and thermal properties of PLA composites were investigated for the first time in the literature. A decrease in the melt viscosity of PLA was obtained from the vertical force measurements in the presence of POSS particles except for high O-POSS loading level. This played an important role for power consumption during micro-compounding process. The mechanical test results showed that, the elastic-modulus and yield strength of the PLA/POSS composites were lower than pure PLA in most cases. Moreover, a significant improvement in Izod impact strength of PLA composites was achieved by incorporation of POSS particles into PLA regardless of POSS type. Morphological analysis showed that POSS particles dispersed homogeneously in polymer matrix for all compositions. The glass transition temperature of PLA decreased with the addition of POSS particles. POSS particles also enhanced the decomposition temperature of PLA. POLYM.

    ABSTRACT: Bamboo fibers reinforced unsaturated polyester (UPE) composites were prepared by compression molding. Effects of fiber extraction, morphology, and chemical modification on the mechanical properties and water absorption of the bamboo fibers-UPE composites were investigated. Results showed that the unidirectional original bamboo fibers resulting composites demonstrated the highest tensile strength, flexural strength, and flexural modulus; the 30–40 mesh bamboo particles resulting composites had the lowest tensile strength and flexural strength, but had comparable flexural modulus with that of chemical pulp fibers. The treatment of bamboo fibers with 1,6-diisocyanatohexane (DIH) and 2-hydroxyethyl acrylate (HEA) significantly increased the tensile strength, flexural strength and flexural modulus, and water resistance of the resulting composites. Fourier Transform Infrared and X-ray photoelectron spectroscopy analyses showed that DIH and HEA were covalently bonded onto bamboo fibers. Scanning electron microscopic images of the fractured surfaces of the composites showed that the treatment of bamboo fibers greatly improved the interfacial adhesion between the fibers and UPE resins. The water absorption kinetics of the composites was also investigated; and the results showed that the water absorption of the composites fitted Fickian behavior well. POLYM.

    ABSTRACT: In this study, a novel method consisting of coating carbon fibers (CF) with graphite nanoplatelets (GnP) is investigated for its ability to modify the mechanical properties in the interphase region. Coating the CF was achieved by immersing CF in a solution of GnP dispersed in an epoxy-based solution for a few seconds. The influence of the processing conditions on the properties of the coating (thickness, homogeneity, quality of the GnP dispersion) is reported. Interfacial adhesion and the associated failure modes were evaluated by the single fiber fragmentation test. The maximum value of interfacial shear strength (IFSS) was achieved when a relative GnP concentration of 7.9 wt% on CFs, which led to 45 and 34% improvements in IFSS in comparison with the non-coated CF and epoxy coated CF, respectively.

    ABSTRACT: Toughened carbon fiber-fabric reinforced polymerized cyclic butylene terephthalate (pCBT) composites were obtained by chemical modification of cyclic butylene terephthalate (CBT) with small amounts of epoxy resin and isocyanates as chain extenders. Homogeneous CBT/epoxy and CBT/isocyanate blends were prepared by melt blending the components in a lab-scale batch mixer at low temperatures and high shear rate. Melt blending was stopped before the ring-opening polymerization of CBT could start. The modified CBT was the starting material for carbon fiber fabric-reinforced pCBT composites (fiber content at about 65 wt%) which were prepared by ring-opening polymerization during compression molding using a simple powder prepreg method. Interlaminar shear strength, flexural strength, and failure strain of the chemically modified composites increased up to 60% with respect to unmodified pCBT composites. Nevertheless, the flexural moduli slightly decreased due to the toughening effect of the chain extender on the pCBT matrix. Drop weight impact tests revealed that the energy absorption of the modified composites was relatively higher as compared to unmodified pCBT composites. POLYM.

    ABSTRACT: To explore the effect of negative thermal expansion on the reduction of the coefficient of thermal expansion of polymer with respect to that of chain stiffening, the preparation of polycarbonate composites with ZrW2O8 and ZrW2O7(OH)2·2H2O are attempted. In the process, the dispersion of the filler particles in the polymer needs to be optimized, and the transfer of properties at the interface between the two phases. Therefore, surface modification by in situ polymerization is performed on these two particles. Several parameters of the reaction are optimized to achieve higher surface coverage of oligomer, including reaction time and the amount of monomers and particles. On the basis of the optimized conditions, two modification steps are then used to maximize both recovered amount of modified particles and surface coverage. The composites prepared with modified particles show enhanced dispersion of the particles and interaction at the interfaces. POLYM. COMPOS., 2014. © 2014 Society of Plastics Engineers

    ABSTRACT: In this study, rice straw (RS) which was one of the major agricultural residues was used as filler in bio-based thermoplastic polyurethane (TPU). Several treatments including hot water, alkali, permanganate, peroxide and silane were applied for modifying the surface of RS. The effects of surface modifications on mechanical, flow, morphological, and water absorption properties of green composites were investigated at a constant 30 wt% RS loading. Silane treatment performed after alkaline treatment gave the highest tensile strength, elastic and storage modulus in mechanical tests and gave the lowest water uptake properties. POLYM.

    ABSTRACT: Chemically functionalized graphene (CFG) is proposed as a novel nanoscale optical heater by uniformly dispersing it in poly(dimethylsiloxane) (PDMS) matrix. And subsequently, a simple, fast, and localized heating method on microfluidic chips is demonstrated. CFG is prepared through simultaneous modification and reduction of graphene oxide with dodecylamine by a solvothermal route. It is well dispersed in PDMS suspension to form uniform CFG/PDMS composite due to the presence of the long-dodecyl chain. The obtained CFG/PDMS composites are readily made into microfluidic chips by standard soft lithography. The localized optical heating on the chip is realized by employing a conventional semiconductor laser as light source. The prepared chips with low to 0.05 wt% CFG contents can exhibit temperature increase (<1 min) at very low power illumination. The optical heating effects were observed not only under irradiation with long wavelength, but also under the wavelengths as short as 405 nm. Our studies illustrated that CFG/PDMS composite can serve as a practical optical heating platform for microfluidic chips with the advantages of simple, low cost, and high efficiency. POLYM.

    ABSTRACT: Layered double hydroxides (LDHs) have attracted much attention as nanofillers in polymer nanocomposites (NCs) due to their particular surface structural, positively charged layer and so on. In this study, a chiral diacid was synthesized by the reaction of tetrabromophthalic anhydride and glutamic acid. LDH was modified by co-precipitation of aluminum nitrate, magnesium nitrate, and glutamic acid containing diacid. Chiral poly(amide-imide) (PAI) was synthesized by direct polycondensation reaction of N-trimellitylimido-l-leucine and 4,4′-diaminodiphenylether. Different NCs of the obtained modified LDHs and the chiral PAI were prepared in a short time using ultrasonic technique. The morphology and the structure of the obtained samples were characterized by Fourier transform infrared, thermogravimetric analysis (TGA), field emission scanning electron microscopy, transmission electron microscopy, and X-ray diffraction analysis. TGA of the NCs showed a special order in thermal stability in compression with the neat PAI owing to the uniform distribution of the nanofillers. POLYM.

    ABSTRACT: Magnetorheological elastomers (MRE) are mainly composed of soft magnetic particles and rubber-like matrix. Previous studies have shown that the matrix has a greater impact on mechanical properties of MRE. In this article, a new kind of polyurethane material was fabricated and used as the matrix of MRE. The effect of several factors on the mechanical properties of MRE samples was experimentally studied, such as fabrication condition, content of iron particles, different weight ratio of castor oil and diphenylmethane diisocyanate, plasticizer. Their microstructures were observed, and the mechanical properties were measured using a testing system in the presence of an external magnetic field. The experimental results demonstrate that these factors have different impact on shear storage modulus, magneto-induced modulus, MR effect and damping property. In addition, the damping property of these MRE is also higher than that of MRE based on the other matrix. This study can hopefully be applied to optimize the mechanical properties of MRE. POLYM.

    ABSTRACT: In this article, chlorosilane-modified ZSM-5 particles were incorporated into polydimethylsiloxane (PDMS) to form mixed matrix membranes (MMMs) for ethanol/water mixture separation via pervaporation (PV). The membranes were characterized by Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, and mechanical performance testing. The maximum loading and dispersion of ZSM-5 into PDMS were improved by chlorosilane modification. To evaluate the PV performance, the MMMs were used to separate an aqueous ethanol solution. The effect of zeolite loading and operational conditions on PV performance was investigated in detail. The separation factor of the composite membranes filled with modified ZSM-5 increased considerably versus unmodified membrane, while the total flux decreased to some degree. Of all the chlorosilane-modified membranes, dodecyltrichlorosilane modified ZSM-5 filled PDMS showed the best separation factor of 15.8 for ethanol. POLYM.
