“…The broadening of the loss modulus peak with long glass fibers in the composites may be due to the increase in the energy absorption by the long glass fibers therein. Thus, the molecular motion due to the matrix resin in the LGF/TPU/PBT/PTW composites was more restricted than that due to without the long glass fibers . The glass transition temperature of the LGF/TPU/PBT/PTW composites at different long glass fibers on loss modulus is showed in Table .…”

Long glass fibers reinforced thermoplastic polyurethane and poly(butylene terephthalate) with the compatibilizer of poly(ethylene-butylacrylate-glycidyl methacrylate copolymer) (LGF/TPU/PBT/PTW) composites were prepared by using self-designed impregnation device. Various rheological plots including viscosity curve, storage modulus, loss modulus, loss angle, Cole-Cole plot, and relaxation spectrum were used to characterization of rheological properties. Dynamic mechanical thermal analysis (DMA) results indicated that "double tan d behavior" of composites is observed. The activation energies of a and b-relaxation process of loss modulus and tan d of the LGF/TPU/PBT/ PTW composites gradually increased with long glass fibers content. Moreover, activation energies for the glass transition relaxation determined from loss tangent peaks are more reliable than using loss modulus criterion. Thermal properties of composites are studied by differential scanning calorimetry (DSC) and thermogravimetric analyses (TGA). Mechanical properties of composites are studied. POLYM.

In this study, the effects of various types of commercial graphene nanoplatelets (XG Sciences xGnP M5, C300, C500, and C750) on the thermal, electromagnetic shielding (EMI SE), electrical and mechanical behavior of an acrylonitrile-butadiene-styrene (ABS) copolymer matrix were investigated. The selected nanofillers were characterized and compared in term of surface area, different oxygen content, dimension and density (X-ray photoelectron spectroscopy, scanning electron microscopy, and helium pycnometry). Graphene nanoplatelets were dispersed in ABS by direct melt compounding at 2, 4, and 8 wt%. Melt flow index (MFI) values almost linearly decreased with all the type of xGnPs, especially with the highest surface area nanofiller (C750). Moreover, EMI SE of neat ABS was improved from 20.7 dB to 22.5 dB (increase more than 3 times) for xGnP (C300, C500, and C750) and to 26.2 dB (increase about 9 times) for xGnP-M5, in agreement with proportional reduction of electrical resistivity. xGnP-M5 also resulted in being most effective in enhancing the tensile modulus which improved up to 64%, while a maximum increment of about 20% was obtained with the others xGnP nanoparticles. However, yield stress slightly decreased for xGnP-M5 (about 29%) and remained fairly constant for others nanofillers. Halpin-Tsai model used to predict the tensile modulus of the nanocomposites suggested that graphene nanoplatelets were randomly oriented in the ABS matrix in a three-dimensional (3D) manner. POLYM.

The performances of rubber-toughened polymers like acrylonitrile-butadiene-styrene (ABS) are strongly affected by the type and amount of rubber phase. Characterization of rubber phase is an effective method to predict and control the physical and mechanical behaviors of ABS materials. In this work, different methods have been employed to determine the amount of rubber phase in ABS polymers. The first method was based on thermogravimetry using a particular step degradation of the polymer. In the second method, characteristic absorption bands in the Fourier transform infrared spectra were used to make a calibration curve to determine the rubber content of unknown ABS samples. The third method was based on variation of heat capacity of ABS polymers with increasing the rubber phase content. In the fourth method, a two-step solvent extraction followed by centrifuging was used to separate the rubber particles of different ABS samples. Separation of hardened rubber particles was used to study the size and size distribution of rubber particles.
