Abstract

Polypropylene (PP), graphite and carbon nanotubes (CNTs) based composites were processed with a co-rotating twin-screw extruder and bipolar plates were produced via injection molding. Two different types of PP were chosen according to their melt flow rates (MFR 8 and 800). In order to understand the influence and the synergistic effect of fillers, graphite content was fixed to 70 weight (wt.) % and flake (with particle sizes 100 m) and spherical (<3 0 m) type graphite were processed as single fillers and mixtures of them. Two different CNT-loadings (1.5 wt.% and 3 wt.%) were used as secondary fillers. Flexural strength tests and in-plane as well as through-plane electrical conductivity measurements were carried out. As primary filler, flak...
