Effect of Blend Ratio on the Properties of Polystyrene/Acrylonitrile Butadiene Styrene/Carbon Black (PS/ABS/CB) Conductive Materials

This research focused the effect of different polystyrene/acrylonitrile butadiene styrene (PS/ABS) blend ratio (0:100, 20:80, 40:60, 50:50, 60:40, 80:20 and 100:0) on the properties of polystyrene/acrylonitrile butadiene styrene/carbon black (PS/ABS/CB) conductive polymer composites (CPCs). Materials were produced through melt blending by using Brabender Plastograph internal mixer. The effect of PS/ABS blend ratio at fixed 15 wt % of CB on the mechanical, electrical, thermal and morphology properties were investigated. The results showed that the flexural strength and modulus reduced as increasing of PS content in PS/ABS/CB CPCs. The storage modulus and transition temperature (Tg) of PS/ABS/CB CPCs decreased with increasing of PS content. The PS/ ABS/CB CPCs at blend ratio of 50:50 showed the highest thermal stability compared to 20:80 and 80:20 at same filler loading.
