P(AAm-co-MAA)/PANI复合水凝胶的制备及pH敏感性增强的研究

摘要

以甲基丙烯酸-丙烯酰胺共聚网络P(AAm-co-MAA)为基体,以聚苯胺(PANI)为互穿组分,制备一种P(AAm-co-MAA)/PANI复合水凝胶.实验表明,P(AAm-co-MAA)表现出pH敏感性.将PANI引入到p(AAm-co-MAA)网络中,使复合水凝胶获得更为优越的pH敏感性以及良好的膨胀可逆性,使复合水凝胶更加适用于药物的负载释放等.%A composite hydrogel composed of cross-linked copolymer of acrylamide-methacrylic acid [P(AAm-co-MAA) ] and polyaniline (PANI) was synthesized.The experimental indicated that the prepared P( AAm-co-MAA) showed pH-responsive characteristics. The polyelectrolyte PANI into the above- mentioned network,the P( AAm-co-MAA)/PANI composite hydrogels obtained an even higher sensitivity to pH environments, good swelling reversibility, which makes it possible to load and release with drugs etc.
