以丝胶蛋白（SS）、丙烯酸（AA）和丙烯酰胺（AM）为主要原料,N,N′-亚甲基双丙烯酰胺（MBA）为交联剂,过硫酸铵（APS）为引发剂,采用水溶液聚合法制备了丝胶蛋白/丙烯酸/丙烯酰胺复合吸水材料,并考察了其在不同条件下的吸水性能。结果表明,SS/AA/AM复合吸水材料在去离子水、自来水、0.9%NaCl溶液中的吸水倍率分别为261 g/g~313 g/g、172 g/g~198 g/g、32 g/g~39 g/g,复合吸水材料的热熔融温度和氧化分解温度发生了变化,热熔融温度从223℃变化到了226℃,说明丝胶蛋白与丙烯酸/丙烯酰胺发生了良好的聚合。
Silk sericine/acrylic acid/acrylamide（SS/AA/AM） composite absorbent material were synthesized by silk sericine,acrylic acid and acrylamide in water when N,N′-methylenebisacrylamide（MBA） was used as crosslinker.and ammonium persulfate（APS） as initiator.The water absorbency performance under different conditions were investigated.The results show the absorbent ratio of SF/AA/AM superbabsorbent polymer in deionized water,tap water and 0.9% NaCl solution is 261 g/g～313 g/g,172 g/g～198 g/g,32 g/g～39 g/g respectively.The melting temperature and oxidative decomposition temperature of the synthesized polymer have changed,the melting temperature have changed from 223 ℃ to 226 ℃,proving that the silk fibroin had polymerized well with acrylic acid and acrylamide.
