Some different proportions of the sol-gel casting solutions were prepared by adding tetraethyl orthosilicate (TEOS) to the mixed polymerthe of quaternized polyvinyl alcohol (QPVA) and poly dimethyl diallyl ammonium chloride (PDADMAC) aqueous solution for the sol-gel reaction. Then each of the casting solutions in the mold was dried to obtain the hybrid membrane. After that the hybrid membranes were cross-linking in the glutaraldehyde solution with acetone to obtain a dimensionally stable hybridization anion-exchange membrane. The effect of the mass ratio of the quaternized polyvinyl alcohol to poly dimethyl diallyl ammonium chloride casting solution on the stability of the hybrid membrane was investigated. The topography, infrared spectroscopy, morphology, thermal stability, the rate of aqueous/methanol, and the ion exchange capacity of four dimensional stability anion-exchange membranes were mainly analyzed. The results showed that the basic hybrid membrane of QPVA/0.25PDADMAC/0.1TEOS was dimensionally stable in methanol, dense in the microstructure, and excellent heat stability in 65-140℃. Meanwhile, the ion exchange capacity could be reached to 1.09141mmol/g, and the basic hybrid membrane had potential applications in alkaline direct methanol fuel cell with low temperature.
