聚苯胺的电荷传输特性及其分子量依赖性
Year: 1998 Journal: Science in China Series B-Chemistry (in Chinese) Vol: 28 (5)Pages: 477-480 Publisher: Science China Press
Abstract
研究了樟脑磺酸掺杂的聚苯胺 (PAn -CSA)膜的导电性对温度的依赖性 ,发现有一个临界温度 (Tc) ,当测试温度高于Tc 时 ,PAn -CSA显示金属的导电特性 ,反之则显示半导体导电特性 .Tc 和聚苯胺的分子量有关 ,分子量越高 ,Tc 越低 .单向拉伸后 ,PAn- CSA膜的电导率大大提高 ,拉伸 6 0 %时 ,室温电导率可达 75 0S/cm ,但Tc不随拉伸而变化
