摘要：

Carbon black(CB)-filled polypropylene(PP) /ultra-high molecular weight polyethylene (UHMWPE) composites were prepared by the conventional melt-mixing method. The electrical resistivity, positive temperature coefficient(PTC) effect, and morphology of the composites were elucidated in detail. CB particles were found to be selectively localized at the interface between PP matrix and UHMWPE particles or in the PP matrix due to the extremely high viscosity of UHMWPE. Double-PTC effects were also observed and discussed.
