Abstract

Over the past decade, rapid progress has been made in the understanding and development of conductive polymer composites (CPCs). The formation processes of composite and composition ratios have significant effects on its electrical and mechanical properties. In this research, focus is given to Graphite (G) as main filler, Carbon Black (CB) and metal fillers such as Iron (Fe) and Aluminum (Al) as second filler of the composites. The multi filler and binder are dry mixed used ball mill with several ratios of composition is selected to produce samples. The weights percentage of CB is increased from 5 % wt. up to 30 % wt. of the total weight percentage of fillers. The mixers were then compounded used Rheomix mixer Haake-PolylabTM with roller type rotors. The shape of this composite was used mold with diameter of 25 mm through compression machine to form disc. The effect of different filler material loading on the properties such as electrical conductivity, bulk density and shore hardness are observed. The result showed the increasing of electrical conductivity as the increased the CB and Fe loading. But for Al, the result showed the decreasing of electrical conductivity as the loading of Al has been increased. Meanwhile the usage of CB clearly shown an improvement in electrical conductivity and able to meet the DOE target properties for development of PEMFC bipolar plate.
