Considerable attention has been given to developing carbon-based polymer composites for applications where high electrical conductivity is required such as for bipolar plates in fuel cells. This study focused on the understanding of the composite electrical conductivity containing PP (polypropylene) and LDPE (Low density polyethylene) as matrix and graphite powder as conductive filler by using injection molding process. The processing conditions have been optimized in an attempt to produce compound material. The PP/G composites was found to have relatively high electrical conductivity compared to LDPE/G at the same wt % of graphite.
