Abstract

Abstract : Polypropylene conductive composites with carbon black selectively distributed at the interfaces between polypropylene matrixes are described by Kun Dai, Zhanhu Guo, and co‐workers in article number1700265 . This segregated conductive network is damaged and constructed by thermal diffusion and aggregation of carbon black, leading to an increasing and then decreasing positive temperature coefficient (PTC) effect.
