在添加和不添加九苯酚聚氧乙烯(n)醚(OPn，其中n=4、7、10、15或21)、十八烷基聚氧乙烯(20)醚(A-20)和十八十聚氧乙烯(10)酯(SE-10)等多种非离子表面活性剂的水溶液中进行电化学聚合。聚吡咯(PPy)的机械性能和表面光滑度添加非离子表面活性剂OPn(n大于或等于7)的水溶液制备的薄膜与不添加表面活性剂的水溶液制备的PPy的薄膜相比有很大改善。以OP10为添加剂，系统研究了添加剂浓度、溶液pH值、溶液阴离子、聚合电流和温度对所制备PPy薄膜力学性能的影响。由pH 2、1 mol/l TsONa、0.1 mol/l 吡咯水溶液添加0.1 mol/l OP10 得到非常光滑柔韧的PPy 薄膜，拉伸强度为127 MPa，电导率为54 S/cm。 (C) 2000 Elsevier Science S.A. 保留所有权利。
The electrochemical polymerization of pyrrole was performed in the aqueous solutions with and without adding various nonionic surfactants such as nonaphenol polyethyleneoxy (n) ether (OPn, where n = 4, 7, 10, 15, or 21), octodecyl polyethyleneoxy (20) ether (A-20) and octodecopolyethyleneoxy (10) ester (SE-10) etc. The mechanical properties and surface smoothness of the polypyrrole (PPy) films prepared from the aqueous solutions with addition of the nonionic surfactants OPn(n greater than or equal to 7) are greatly improved in comparison with those of the PPy prepared from the aqueous solutions without the surfactants. With the OP10 additive, the effect of the additive concentration, pH value of the solutions, solution anions, polymerization current and temperature on the mechanical properties of the as-prepared PPy films were studied systematically. Very smooth and flexible PPy film with the tensile strength of 127 MPa and the conductivity of 54 S/cm was obtained from pH 2, 1 mol/l TsONa, 0.1 mol/l pyrrole aqueous solution with the addition of 0.1 mol/l OP10.
