Due to the special ion transfer characteristic in ion exchange membranes，the electro-membrane processes based on ion exchange membranes can achieve the separation and classification of the ions，which have found more and more important applications in clean production，energy-saving and emission reducing，environmental protection，and energy conversion. The ion exchange membranes processes meet with the demands of energy-saving，reuse of raw material，and pollution prevention in modern industries，and have become one of the key components for sustainable development in our economy. However，the preparation and applications of homogenous in exchange membranes are still at infant stage of development in China due to technological embargoes and price monopoly by the Japan leaded developed country. As a consequence，it is of great significance for the development of some novel membrane preparation routes. A one-step preparation route of homogenous exchange membranes by polyacylation of ionized monomers was developed in our lab. The ATRP technology was used to manipulate the structure of ion exchane membranes to achieve the constrcution of hydrophobic structure in the main chain and hydropholic in the side chain by controlling graft density and graft length of the side-chain pendant. The prepared membranes by this strategy will meet the demands of different applications. The indutrial preparation of this kinds of ion exchange membranes can breakthourgh the technological embargoes and price monopoly the Japan of leaded developed country and can achieve development of the independent intellectual property rights in exchange membranes production. The preparation route is very simple and effective with a moderate operation condition. The quarternization and sulfonation steps were avoided in our preparation route with a simplified preparation steps and a reduced pollution. Our preparation route meets with the demand of high-effective membranes in diffusion dialysis，conventional electrodialysis and bipolar membranes electrodialysis. The prepared membranes were tested with satisfactory results in many different processes such as special wastewater treatment，organic acids production，amino acid separation and purification，and heavy metal wastewater treatment.
