摘要
以N,N’-亚甲基双丙烯酰胺为交联剂、过硫酸铵和焦亚硫酸钠为氧化还原引发剂,采用新型两步水溶液聚合法制备了聚丙烯酸盐/淀粉半互穿网络水凝胶。探讨了其溶胀动力学、保水性及离子强度敏感性,研究了对甲基橙染料在盐溶液中的释放性能。
Novel polyacrylate/starch semi-interpenetrating network （IPN） hydrogels were synthesized via two-step aqueous solution polymerization in the presence of a crosslinker of N, N＇- methylene bisacrylamide （NMBA）, using ammonium persulfate （APS） and sdium pyrosulfite as the redox initiator. The swelling kinetics, water retention and ionic strength sensitivity were investigated and release property of methyl orange dye in salt solutions was researched.
