A pure organic PEDOT:PSS nanofilm was used as a working electrode for the first time to electrodeposit polymer films of polythiophene (PTh) and its derivatives in a boron trifluoride diethyl ether (BFEE) solution, fabricating a novel generation of bilayered nanofilms. Cyclic voltammetry (CV) demonstrated good electrochemical stability of the as-formed films. Structures and surface morphologies were systematically investigated by the characterizations of cross-section SEM, FT-IR, UV-vis, SEM, and AFM. The resulting films revealed stable and enhanced thermoelectric (TE) performances. The electrical conductivity values of PEDOT:PSS/PTh, PEDOT:PSS/P3MeT, and PEDOT:PSS/P3HT nanofilms were determined to be 123.9, 136.5, and 200.5 S cm(-1), respectively. The power factor reached up to be a maximum value of 5.79 μW m(-1) k(-2). Thus, this technique offers a facile approach to a class of bilayered nanofilms, and it may provide a general strategy for fabricating a new generation of conducting polymers for more practical applications.
首次使用纯有机聚 3,4-乙烯二氧噻吩：聚苯乙烯磺酸（PEDOT:PSS）纳米薄膜作为工作电极，在三氟化硼乙醚（BFEE）溶液中电沉积聚噻吩（PTh）及其衍生物的聚合物薄膜，制备了新一代双层纳米薄膜。循环伏安法（CV）证明了所形成薄膜具有良好的电化学稳定性。通过截面 SEM、FT-IR、UV-vis、SEM 和 AFM 的表征，对结构和表面形貌进行了系统研究。所得薄膜表现出稳定且增强的热电（TE）性能。PEDOT:PSS/PTh、PEDOT:PSS/P3MeT 和 PEDOT:PSS/P3HT 纳米薄膜的电导率值分别确定为 123.9、136.5 和 200.5 S cm(-1)。功率因子高达 5.79 μW m(-1) k(-2)的最大值。因此，该技术为双层纳米薄膜提供了一种简便的方法，可能为制造新一代用于更实际应用的导电聚合物提供了一种通用策略。
