摘 要:在十二烷基苯磺酸存在下,用原位乳液聚合技术聚合苯胺,制得了聚苯胺和磺化乙丙橡胶(EPDM)锌离聚体复合物,EPDM锌离聚体由EPDM磺化及中和制得.用磺化度分别为0.10,0.24,0.40mmol/g的EPDM锌离聚体作为基质制备出各自的复合物,复合物可以熔融热塑加工,其电导率呈现的渗滤阈值为13%.在聚苯胺质量分数相同的情况下,磺化度小的复合物的电导率高于磺化度大的复合物.当磺化度为0.10mmol/g、聚苯胺质量分数为6%~11%和磺化度为0.24mmol/g、聚苯胺质量分数为2%~11%时,复合物表现出热塑性弹性体的行为,扯断伸长率达200%~500%,永久变形小于40%.用间甲酚进行二次掺杂后复合物的电导率有所提高.加入硬脂酸锌会降低复合物的电导率及力学性能.
