Abstract：

With polysulfone（PSF）, ethyl chloride isocyanate and 4 - diethyl amino phenol reagent, a kind of quaternary ammonium of polysulfone (PSF-QN) membrane material with a long flexible side chain was prepared based on one pot methods by two step. And then a kind of crosslinking type polysulfone anion exchange membrane (CPSF-BN) was constructed by crosslinking reaction with 1, 4 – dibromobutane as small molecule reagent. After characterizing the chemical structure of the modified polymer by infrared spectral. Water uptaking(WU), dimensional stability(SW) and alkali resistance of anion exchange membrane were studied. The experiment result was found that the phase separation structure was strengthen by locating the hydrophilic region far away from hydrophobic regions. At the same time, a network structure is formed by chemical crosslinking. The combination of these two factors solves the problem of poor dimensional stability and alkali resistance of anion exchange membrane under high water absorption. With the increase of temperature, the water absorption rate (WU), water absorption swelling rate (SW) and ion conductivity of CPSF-BN AEM increase. The ion conductivity of CPS-HN-3 AEM with IEC 1.53mmo/g at room temperature and 85℃ are 0.035 S/cm and 0.083S/cm. The swelling ratio are only 14.1% and 25.8%. The AEM maintained good dimensional stability and alkali resistance due to the retention of conductivity reached 83.2% after soaking in strong alkali for 30 days. It is expected to be used in practical applications of fuel cells.
