采用循环伏安法电化学聚合制备了聚吡咯(PPY)/聚砜(PSF)复合膜,结果发现:复合膜的正面(与工作电极接触的一面)是黑色的,而反面(与溶液接触的一面)是白色的。复合膜的表面形态和化学组分分别用扫描电子显微镜(SEM)和红外光谱(FTIR)进行了表征,讨论了吡咯和聚砜的含量对复合膜性能的影响,分析了复合膜的形成过程。
(PPY) / polysulfone (PSF) composite films were prepared by cyclic voltammetry. It was found that the front side of the composite film (the side in contact with the working electrode) was black and the opposite side One side) is white. The surface morphology and chemical composition of the composite membrane were characterized by scanning electron microscopy (SEM) and infrared spectroscopy (FTIR), respectively. The effects of pyrrole and polysulfone on the properties of the composite membrane were discussed. The formation process of the composite membrane was also analyzed.
