Percolation Threshold and Morphology of Composites of Conducting Carbon Black/ Polypropylene/EVA

摘要

Conducting carbon black(CB) was added to PP to prepare conducting composites by the melt processing method.EVA was added to the composites to lower the percolation threshold.The percolation threshold of the ternary CB/PP/EVA composites was only 3.8 vol%,while it was up to 7.8 vol% for the binary CB/PP composites without EVA.
