摘    要:本文以丙烯酰胺(AM)、2-丙烯酰胺基-2-甲基丙磺酸(AMPS)为有机单体、正硅酸乙酯(TEOS)为无机原料合成了P(AM-co-AMPS)基水凝胶,研究了凝胶的相转变温度,以及在相转变温度前后的溶胀性能和溶胀动力学。结果表明,P(AM-co-AMPS)凝胶在25℃水温下主要以大分子松弛为主的溶胀方式,而在0℃水温下为Fickian扩散方式,且具有一定的温敏性;P(AM-co-AMPS)/SiO2杂化凝胶在0℃和25℃均保持非Fickian扩散方式,且温敏性被掩盖。

Abstract:In this paper,the hydrogels were prepared with the copolymer of acrylamide(AM) and 2-acrylamide-2-aethylpropanesul-fonic acid(AMPS) as the organic phase,introducing silicon dioxide(SiO2) as inorganic phase which obtained by Ethyl silicate(TEOS).The phase inversion temperature,swelling behavior and swelling kinetic in water at temperatures(25℃ and 0℃) of the hydrogels were studied.It was showed that P(AM-co-AMPS) hydrogels swelling mechanism belong to macromolecule relaxation at 25℃,but belong to Fickian diffusion at 0℃ yet,indicating that they are temperature-sensitive,while P(AM-co-AMPS)/SiO2 hybrid hydrogels swelling mechanism all belongs to non-Fickian diffusion at 25℃ and 0℃,and the temperature-sensitive of these hybrid hydrogels are vanished.
Keywords:Hybrid hydrogels  Kinetic  Interpenetrating network
