摘要

導電高分子結構龐大、分子量高並且本身具有導電性的物質。其導電度可藉由改變加工方法、摻雜條件、共摻合等方法加以調整，故可應用於電池、防靜電材料、感測器和電子儀器等元件。
利用循環伏安法的聚合便利性，來製備吡咯與新型苯胺的共聚物，並觀察在高溫下是否會破壞其結構。因聚砒咯的耐熱性質不佳，所以我們在苯胺衍生物側鏈上加入一些耐熱性質好的矽氧烷，來達到增加砒咯的耐熱性質。此外，聚苯胺單體便宜、製備容易，所以將苯胺與噻吩及吡咯分別共聚合，以低廉的苯胺得到高附加價值的共聚合物，對環境和熱皆有良好的穩定度。
最後，電聚合聚苯胺、聚吡咯的過程中，添加不同的摻雜劑，觀察其導電度之影響，實驗過程中發現不管是溶劑、電解質和摻雜劑的改變，都會影響其導電度。電化學合成導電高分子代替傳統繁複的有機合成方法，可以節省更多時間和成本，是目前普遍受到歡迎的方法。
