【摘要】 本文用共混法制备了炭黑(CB)、碳纤维(CF)、碳毡(CFF)填充低密度聚乙烯(LDPE)导电复合材料,研究了复合材料的PTC性能,分析了PTC效应产生的原因和影响PTC性能的因素,并提出了改善材料PTC性能的方法。更多还原

【Abstract】 Conductive composite was prepared by blending carbon black (CB), carbon fiber (CF) and carbon fiber felt (CFF) and LDPE in this paper. The positive temperature coefficient (PTC) behavior of the composite and the reason was dicussed. On the basis of studies on factors that influenced the PTC properties, the approach to improve the PTC properties was analyzed.更多还原
