多孔敏感聚丙烯酰胺水凝胶的合成及性能研究
Synthesis and properties of Macropore sensitive PAAM Hydrogel
用N,N’-亚甲基双丙烯酰胺(BIS)做交联剂,聚乙二醇-6000(PEG)做致孔剂,采用交联聚合的方法合成了两种水凝胶。对两种产物进行了表征,结果表明PEG-6000只充当致孔剂的作用而不参与聚合。我们研究了两种凝胶的溶胀、去溶胀动力学,及其溶胀率随温度、pH、离子强度的变化趋势,结果表明PEG-6000修饰的丙烯酰胺水凝胶性能较好;定性研究了这种水凝胶在各种条件下(不同温度、酸性条件)吸附铜离子的动力学。
wo kinds of hydrogels were synthesized using BiS as crosslinker and polyethyleneglycol PEG-6000 as poring-agent by means of crosslinking polymerization method. The products were characterized , which show that PEG-6000 only act as poring-agent, not participate in polymerization. Kinetics of swelling, reswelling and swelling ration changing following temperature, pH, ionic strength, which show that PEG-6000 hydrogel has a better proterty. At various conditions, kinetics of one hydrogel absorbing copper ion was qualitative study, which show that there was absorption optimum condition.
