摘要: 借助WAXD、SAXD和DSC等手段研究了炭黑与聚乙烯复合体系在不同热处理条件下的结晶行为及聚集态结构的大尺寸效应对PTC特性的影响。由此提出,不仅结晶度大小,而且聚集大尺寸效应性能对PTC行性有重要影响的新观点。Abstract: In this paper, the effect of the behavior of melting and crystallization, long spacing and crystal particle size in polyethylene/CB composite on PTC properties were investigated by means of WAXD, SAXS, DSC et al The experimental re
