【摘要】:为利用溶剂化效应来优化液相沉降聚合聚3,4-乙撑二氧噻吩(PEDOT)的结构和光电性能,将吸附Fe(OTs)3的聚对苯二甲酸乙二醇酯(PET)膜悬于含乙腈的EDOT环己烷溶液中,于60℃原位合成PEDOT涂层。以紫外-可见吸收光谱、X射线光电子能谱分析所合成PEDOT的共轭链结构和掺杂度,以四探针测量表面电阻,研究乙腈含量对合成PEDOT结构与性能的影响。当乙腈体积分数为0.05%时,添加的乙腈能抑制短共轭链的生成,提高掺杂度,在降低表面电阻的同时,改善透光率。乙腈体积分数在0.24%以内时,PEDOT的导电性随乙腈体积分数的上升而增加。当乙腈体积分数超过0.7%时,PEDOT中短共轭链数目增加,光电性能下降。当乙腈体积分数为8%时,由于吸附的Fe(OTs)_3溶解太快,无法在PET表面合成导电PEDOT膜。乙腈体积分数为0.24%时,获得的PEDOT膜的表面电阻可达174Ω,透光率80%,粘附力为5B级。
