摘要：

Novel anion exchange membranes based on the copolymers of 1-allyl-3-methylimidazolium chloride (AmimCl) ionic liquid either with methyl methacrylate (MMA) or butyl methacrylate (BMA) have been prepared via free radical polymerization The structures and characteristic properties of the membranes are studied It is found that the hydroxyl ionic conductivity of the synthesized membrane can reach 3 33 x 10(-2) S cm(-1) in deionized water at 30 degrees C. The methanol permeability is less than 10(-9) mol cm(2) s(-1) even at 60 degrees C. These membranes with imidazolium salt functional groups exhibit superior stability both chemically and thermally as well compared to the alkyl quaternary ammonium functionalized polymers Therefore, the membranes have good perspectives and great potential for alkaline fuel cell applications.
