聚苯胺/碳纳米管杂合水凝胶的合成及膨胀性能研究

摘要

合成了一种以甲基丙烯酸-丙烯酰胺共聚网络P(AAm-co-MAA)为基体,以聚苯胺为互穿组分(PANI)的半互穿网络杂合水凝胶.研究表明,当将PANI和MWNTs-COOH被引入到P(AAm-co-MAA)网络中后得到的p(AAm-co-MAA)/PANI/MWCNT-COOH半互穿网络杂合水凝胶则能保持较好的膨胀性,同时发现,依靠调节PANI/MWNTs-COOH的含量可以使杂合水凝胶膨胀性增加.这为研究杂合水凝胶的力学性能和pH敏感性提供了一个窗口.%A hybrid hydrogel with semi-interpenetrating networks (semi-IPN) composed of cross-linked copolymer of acrylamide-methacrylic acid [ P (Aam-co-MAA) ] and polyaniline ( PANI) and carboxylfunctionalized multi-walled carbon nanotubes (MWNTs-COOH) was synthesized. The hydrogel with an excellent swelling performance can be constructed by adjusting or modulating the concentration of the conducting component PANI/MWNT-COOH. It provided a window for studying pH-sensitive properties and mechanical property of the hydrogel.
