中文摘要	Three kinds of polyvinylidene fluoride (PVDF) based ion exchange membranes were prepared, their area resistance,ion exchange capacity (IEC), water content and vanadium ion permeability ratio were compared. The PVDF-sodium allylsulfonate (SAS) membrane prepared with a homogeneous solution of PVDF and SAS had the lowest area resistance of 1.2 Omega middot cm/sup 2/, its IEC was 1.16 mmol/g. FT-IR analysis showed that the C = C bond of SAS polymerized after long time under high temperature and formed inter network structure with PVDF during the processes of the membranes formation. Self-discharge test showed that the vanadium ions permeation rate of the prepared membrane was below 8.8 * 10/sup -3/ V/h at open circuit condition.
