Resilient anion exchange membranes prepared by polymerizing a composition

摘要

A resilient anion exchange membrane including a homogeneous cross-linked ion-transferring polymer substantially filling pores and substantially covering surfaces of a porous substrate, wherein the resilient anion exchange membrane is prepared by polymerizing a composition including a quaternary ammonium cationic surfactant monomer, a crosslinking monomer including two or more ethylenic groups, a free radical initiator, and a solvent.
