摘要
以N-异丙基丙烯酰胺(NIPAM)和丙烯酸(AA)为原料,通过水相溶液聚合法制备P(NIPAM-co-AA)水凝胶.傅里叶变换红外光谱仪(FT-IR)的结果表明,以N-异丙基丙烯酰胺(NIPAM)和丙烯酸(AA)为原料成功制备了P(NIPAM-co-AA)水凝胶;扫描电镜的结果表明,P(NIPAM-co-AA)水凝胶具有规整的孔洞结构;热重-差示扫描量热仪(TG-DSC)的结果显示,P(NIPAM-co-AA)水凝胶具有良好的热稳定性.测定P(NIPAM-co-AA)水凝胶在不同温度及p H值条件下的溶胀度,结果表明P(NIPAM-co-AA)水凝胶具有良好的温度及p H响应性,能在不同外界环境的刺激下做出不同的反应,具有强大的智能性.
P（ NIPAM-co-AA） hydrogels were prepared by aqueous solution polymerization. The FT-IR results showed that P（ NIPAM-co-AA） hydrogel was successfully prepared from N-isopropylacrylamide（ NIPAM） and acrylic acid（ AA）. The SEM results showed that P（ NIPAM-co-AA） hydrogel has a regular pore structure. TG-DSC results showed that P（ NIPAM-co-AA） hydrogel has good thermal stability. By measuring the swelling degree of P（ NIPAM-co-AA） hydrogels under different temperature and p H conditions,the results showed that P（ NIPAM-co-AA） hydrogels had good temperature and p H responsive properties,This suggested P（ NIPAM-co-AA） hydrogels make different responses under different environmental stimuli and have a good intelligence.
