电化学合成高取向的聚（3、4-乙撑二氧噻吩）薄膜

发布时间：2021-07-19 10:12

　　1970年代后期,出现了新型聚合物,即有机导电聚合物（OCP）,由于其独特的热,电和光学特性以及其广泛的应用,吸引了许多材料科学家,物理学家和化学家的研究人员对其进行深入研究。聚（3,4-乙撑二氧噻吩）（PEDOT）是迄今为止热,电和光学稳定性最好的OCP之一。我们通过循环伏安法在取向高密度聚乙烯（HDPE）薄膜上制备高取向PEDOT薄膜。在乙腈溶液中,采用氧化铟锡涂层玻璃（IT0）电极上进行了电化学合成并用5%的HCI掺杂PEDOT。扫描电子显微镜,傅里叶红外光谱,偏光显微镜,偏振拉曼光谱和紫外光谱表明获得了各向异性的PEDOT薄膜。PEDOT薄膜表现出各向异性的导电率。垂直于HDPE膜的拉伸方向的电导率是5.2 S · cm-1,高于水平方向的0.28 S · cm-1。两个方向之间电导率的显著差异表明:外延电化学沉积是获得高性能导电聚合物的有效方法。PEDOT薄膜已显示出具有最紧凑的形态,较小的表面粗糙度。电化学研究表明,PEDOT具有较高的电容电流。这些特性使PEDOT适合用作全固态离子选择电极中的固体触点。
