摘要
采用后磺化方法,以氯丁酰氯(CBC)和对羟基苯磺酸钠(HBSS)为小分子试剂,通过两步反应制备一种侧链型磺化聚砜PS-HS,采用FT-IR和1H-NMR对它们的结构进行表征;采用流延成膜法制备相应的PEM,研究了PEM的基本性能,结果表明:该PEM表现出较好的吸水率(WU)、尺寸稳定性(SW)和质子传导率,室温时的质子传导率高达到0.049S/cm,SW仅为7.1%,溶胀率甚至低于市售的Nafion115和Nafion117膜。
By post-sulfonation method,a kind of side chain type sulfonated polysulfone（ PS-HS） was obtained according to two chemical reaction with chlorobutyryl chloride and p-hydroxybenzenesulfonate Sodium as reagent.The proton exchange membrane（ PEM） were prepared by casting method on basis of characterizing their chemical structure. The basic properties of PEM were studied,the result showed that the PEM had good performance in waterupaking（ WU）,swelling ratio（ SW） and proton conductivity,the proton conductivity was up to 0. 049 S/cm and the swelling ratio（ SW） was only 7. 1% at room temperature,low than Nafion115 and Nafion117.
