化學聚合奈米共軛高分子

導電性高分子聚苯胺(polyaniline, PANI)因其合成方法簡易、對水和空氣穩定性佳、成本低廉，可藉由氧化還原態的改變控制導電度，也可藉由質子酸摻雜反應控制，所以近來應用在電子相關領域非常熱門。本實驗利用化學聚合法，成功製備出PANI，又分兩種方法：第一種為界面聚合法，分三部分：第一部份為利用ANI、使用HCl當摻雜酸，過硫酸胺(Ammonium peroxodisulfate, APS)為氧化劑、氯仿為有機溶劑，改變不同比例氧化劑，成功製備出在水相的PANI；第二部份將HCl改為十二烷基苯磺酸(Dodecyl benzene sulfonic acid, DBSA)，以相同方法製備出在有機相的PANI；第三部分，以固定比例ANI、APS、DBSA探討改變不同有機溶劑(氯仿、乙酸乙酯、甲苯)所合成之聚苯胺差異。第二種為乳化聚合法，固定ANI、HCl，改變不同比例APS和DBSA，合成出聚苯胺經抽氣過濾、烘乾，並用FTIR和四點探針測其官能基和導電度。因聚苯胺成膜性不佳，所以我們利用甲苯當溶劑，將聚苯胺粉末與塑膠粒ABS、PMMA進行摻合製成薄膜增加其應用性。
