PAA was blended with Carboxymethyl Cellulose (CMC) and then cross-linked by Cr3+ to prepare mPAA/CMC. Chitosan (CS) was cross-linked by glutaraldehyde (GA) and di-n-butyltin dichloride. mPAA/CMC-mCS bipolar membrane was prepared by casting technique. IR spectrum indicated that the anion and cation membranes contain-NRH2+,-COO- functional groups, respectively. It had high ion exchange capacity and good permeability. The mPAA/CMC-mCS bipolar membrane was applied in the electro-synthesis of TMAH.
