摘要: Abstract In this study, composite cation exchange membranes (C-CEMs) based on polyvinyl pyrrolidone (PVP) and mainchain sulfonated polyethersulfone (SPES) were prepared by adding conducting polyaniline (PANi). The electrodialysis (ED) properties of these C-CEMs characterized to determine their feasibility for practical applications. exhibited smooth surfaces dense cross-sections when PANi was homogeneously dispersed in the matrix material. An increase C-CEM mechanical stability attributed formation a crosslinked structure. experimental results showed that with 0.6% possessed highest ionic conductivity. ED process better desalination than those other commercial CEM. On whole, an appropriate content improved properties. This study detailed new method preparation novel, low-cost It found optimal improving membrane performance.
