为改善聚乙撑二氧噻吩:聚(对苯乙烯磺酸)根阴离子(PEDOT:PSS)薄膜的光学及电学性能,采用共混一旋涂法在石英玻片上制备出山梨醇掺杂的PEDOT:PSS透明导电膜.利用X射线衍射仪(XRD),傅立叶变换拉曼光谱(FT-RM),原子力显微镜(AFM),场发射扫描电子显微镜(FE-SEM),紫外-可见吸收光谱(UV-Vis)及四点探针法对薄膜的微结构与性能进行了研究.XRD结果显示山梨醇的掺杂未改变薄膜的聚集态结构;FT-RM表明PEDOT的主要特征峰发生红移,主链结构发生苯-醌转变,分子间作用力增大,导致薄膜表面粗糙度增大,横截面出现索状条纹;薄膜透光率在600～900 nm略有升高,导电性能有较大提高,最佳掺杂浓度下,薄膜电导率可达到105 S/cm.
