1970年代后期,出現(xiàn)了新型聚合物,即有機(jī)導(dǎo)電聚合物（OCP）,由于其獨(dú)特的熱,電和光學(xué)特性以及其廣泛的應(yīng)用,吸引了許多材料科學(xué)家,物理學(xué)家和化學(xué)家的研究人員對(duì)其進(jìn)行深入研究。聚（3,4-乙撐二氧噻吩）（PEDOT）是迄今為止熱,電和光學(xué)穩(wěn)定性最好的OCP之一。我們通過循環(huán)伏安法在取向高密度聚乙烯（HDPE）薄膜上制備高取向PEDOT薄膜。在乙腈溶液中,采用氧化銦錫涂層玻璃（IT0）電極上進(jìn)行了電化學(xué)合成并用5%的HCI摻雜PEDOT。掃描電子顯微鏡,傅里葉紅外光譜,偏光顯微鏡,偏振拉曼光譜和紫外光譜表明獲得了各向異性的PEDOT薄膜。PEDOT薄膜表現(xiàn)出各向異性的導(dǎo)電率。垂直于HDPE膜的拉伸方向的電導(dǎo)率是5.2 S · cm-1,高于水平方向的0.28 S · cm-1。兩個(gè)方向之間電導(dǎo)率的顯著差異表明:外延電化學(xué)沉積是獲得高性能導(dǎo)電聚合物的有效方法。PEDOT薄膜已顯示出具有最緊湊的形態(tài),較小的表面粗糙度。電化學(xué)研究表明,PEDOT具有較高的電容電流。這些特性使PEDOT適合用作全固態(tài)離子選擇電極中的固體觸點(diǎn)。
