1. 毕业设计（论文）的内容和要求

采用双辊开炼的方法制备具有不同cb含量和cb在不同组分的pp/sbs/炭黑共混物。

首先，在聚丙烯（pp）中加入不同量的炭黑（cb）制备不同cb含量的pp，研究不同cb含量对pp力学性能和导电性能的影响；其次，制备具有不同cb含量的苯乙烯-丁二烯-苯乙烯嵌段共聚物（sbs）,研究不同cb含量对sbs力学性能和导电性能的影响；最后，分别先在pp中加入cb再和sbs共混，先在sbs中加入cb再和pp共混，先pp和sbs共混再加入cb，制备cb在不同组分中的pp/sbs共混材料，研究cb在不同组分中对共混物的力学性能、导电性能的影响，并提出导电机理。

实验采用模压法制备样品，并借助电子万能试验机、高阻计、扫描电子显微镜（sem）、傅里叶变换红外光谱仪（ftir）等，分析制备共混物的力学性能、导电性能、相容性等。
