Abstract: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.
