【Abstract】 This paper summarized the recent research progress of anion exchange membrane from the preparation materials of anion exchange membrane; the preparation methods and the analysis of the anion exchange membrane surface modification. The main preparation materials of anion exchange membrane were chitosans, polysulfones, benzene ethers and polyvinyl fluoride. There were two most common preparation methods for anion exchange membrane: one was starting from a monomer, polymerized into the base film, then functional for anion exchange membrane; the other made polymer as substrate, by phase inversion method for base film.Current performance modification of the anion mainly focused on stain resistance, monovalent and diatomic ion separation, mechanical strength, and chemical stability. In the field of fuel cells and sewage treatment, the anion exchange membrane had broad application.The high performance, low cost, new type, and environment protecting is also the current need to develop the material.更多还原
