Abstract: The alloy of Nylon6/Acrylonitrile-Butadiene-Styrene (ABS) with styrene-maleic anhydride (SMA) was prepared by melt blending as the compatilizer. Mechanical characteristics, dynamic mechanical analysis (DMA) and fracture appearances were determined. It was found that the impact and tensile strength firstly increased and then decreased along with the increase of the SMA content. The properties reached maximum values when the content of SMA was 2%. The results of DMA and scanning electron microscope (SEM) indicated that the addition of SMA can effectively enhance the compatibility of Nylon6 and ABS.

Abstract: Different content of aluminum powder was mixed into natural rubber. Aluminum powder was modified by different coupling agents via wet method, and the modified aluminum filler/NR composite was prepared. The mechanical properties, thermal conductivity and thermogravimetric analysis of the composites was investigated. The results showed that the best physical properties and thermal conductivity of composites were achieved with saline coupling agent Si-69, and Thermo decomposing temperature of 3%TM-38S matching composites improved evidently. SEM test indicated that boundary surface of aluminium fillers and rubber was obviously improved when aluminum powder was modified by coupling agent, which would result in preferable mechanical property. The result of Thermogravimetric analysis showed that after aluminum powder filler was modified by three coupling agents, thermo decomposing temperature and hot lost weight of composites rose obviously. With the increase of Al powder content the thermal conductivity improved greatly, Thermal conductivity of Al/NR composites lay between 0.25 and 0.47 W·m^-1·K^-1.
