Morphology and Properties of Conductive Carbon/Polyolefins Composite

Conductive polymer composite materials are fabricated by mixing high density polyethylene or polypropylene with conductive fillers. To overcome the deterioration in mechanical properties of carbon-polymer composites with high carbon loading, ethylene-propylene rubber is blended into the composites. The electrical and mechanical properties of the composite materials are studied. Because blending of polymeric phase with conductive particles influences the morphology which in turn affects the performance of the final composite, the morphology and microstructure of the blends and that of the composites are examined as well.
