摘　　要：以聚砜为基材制备阴离子导电膜材料。将季膦化聚砜铸膜液与已证实成膜性能良好的季铵化聚砜共混,制备QAPSFOH/QPPSFOH共混阴离子交换膜,以改善季膦化聚砜成膜困难问题。通过改变两种成分比例,可以得到不同性能的阴离子交换膜。在QAPSF与QPPSF摩尔比为1∶2时,共混膜电导率达0.030 9 S/cm,拉伸强度达775 MPa,热分解温度达160℃,满足实际情况对阴离子交换膜的需要。The anionic conducting membrane material was prepared based on polysulfone in this work. Casting solution of quaternary phosphonium PSF blended with quaternary ammonium polysulfone which exhibits excellent mechanical properties to prepare of a novel kind of anion exchange membrane QAPSFOH / QPPSFOH. The blend membrane can improve the difficult question of quaternary phosphonium PSF to form a membrane. By changing the ratio of the two components can obtain different performance anion exchange membranes. When QAPSF： QPPSF material mol ratio of 1：2, the conductivity of the blend membrane was up to 0.0309 S/cm, tensile strength was up to 775 MPa, thermal decomposition temperature can reach 160℃. The anion exchange membrane have been met the requirements of the theory.
