【摘要】 采用原位聚合法，在ＳＩＳ／ＬＰＢ交联橡胶基体中合成聚苯胺，形成半互穿网络结构的导电橡 胶复合体。复合物的导电性能良好，当ｍ（ＴＭＰＴＡ）／ｍ（ＳＩＳ）＝０．５ｇ／１．０ｇ及ｍ（Ａｎ）／ｍ（ＳＩＳ）＝０．８ｇ／ １．０ｇ时，电导率可达１７０Ｓ／ｍ，此时复合物的力学性能仍较好，其拉伸强度和扯断伸长率分别为 ６．８ＭＰａ和８５．３％。更多还原

【Abstract】 Polyaniline was synthesized within the crosslinked SIS/LPB rubber matrix by the in-situ polymerization to form a conductive rubber composite with the structure of Send-interpentrating network. The composite has excellent conductive property. The conductivity is up to 170S/m when m(TMPTA)/m(SIS) = 0.05g/l .0g and m(An)/m(SIS) = 0. 8g/l .0g while its mechanical Properties are still good. At this point, the tensile strength and elongation are 6. 8MPa and 85. 3% respectively.更多还原
