Polyelectrolyte complex/PVA membranes for diffusion dialysis

Polyelectrolyte complexes (PECs)/polyvinyl alcohol (PVA) membranes are prepared from PVA, anion exchange and cation exchange multisilicon copolymers. Covalent network through SiOSi bonding, electrostatic interaction between N+(CH3)3 and SO3 groups and hydrogen bonding are present to strengthen the membrane structure.
