Through the research of crosslinking of matrix resin , heating treatment of composite and mixing of different polymer , we draw some conclusions : 1 、 percolation theory can explain the phenomenon of the jump of resistance when the content of cb reach a critical volume ; 2 、 based on ohm conduct theory , abounded to the percolation the wbibull statistical theory and other theory , an adapted theory was obtained to explain the jump of resistance and the other phenomenon ; 3 、 the ntc phenomenon was eliminated by crosslinking the matrix of conductive composite , at the same time the stability of composite was improved 通过对基体树脂的交联、复合材料的热处理、聚合物共混物的研究得出了如下的结论: 1 、渗滤理论能够很好的解释导电粒子含量达到某一值时电导率剧增的问题; 2 、在欧姆导电模型的基础上,综合应用了weibull统计理论模型,结合原来的体积膨胀等理论,成功的解释了ptc复合材料在基体材料熔点附近的跳变问题、 ntc现象以及热循环稳定性等问题; 3 、有机ptc导电复合材料经硅烷交联以后能够消除ntc现象,改善了导电复合材料的稳定性能。
With the increase of silane content , the content of gelatin increased continuously and ntc phenomenon disappeared gradually . when the silane content reach a certain volume , the ntc phenomenon was eliminated completely , at one time , the content of gelatin keep stable . 4 、 heating treatment can improve ptc characteristic of composite and increase ptc intensity . when the temperature and time of 随着硅烷含量的增加凝胶含量不断的增加, ntc现象逐渐消失,达到一定值时ntc现象消失,凝胶含量不再提高; 4 、热处理可以改善导电复合材料的ptc特性,提高它的ptc强度,热处理温度为120 ,热处理时间为30h时效果最为明显。
