摘　　要：以N-异丙基丙烯酰胺(NIPAM)和N-(3-二甲氨基丙基)甲基丙烯酰胺(DMAPMA)为单体,N,N-亚甲基双丙烯酰胺做交联剂(MBA),通过乳液聚合法制备了一种新型共聚微凝胶Poly(NIPAM-co-DMAPMA)。采用扫描电子显微镜和动态光散射仪对微凝胶的表面形貌和粒径进行分析,研究了微凝胶自身可逆相转化过程,通过变温捕集释放实验分析了微凝胶乳液对CO_2的捕集性能。结果表明:Poly(NIPAM-co-DMAPMA)微凝胶呈规则球形,颗粒粒径分布均匀、可逆稳定性好,对温度具有良好的响应能力,能够对CO_2进行可逆捕集与释放。A novel type of copolymer microgels (Poly(NIPAM-co-DMAPMA))were synthesized by emulsion polymerization using N-isopropyl acrylamide (NIPAM)and N-[3-(dimethylamino)propyl] methacrylamide (DMAPMA)as monomers,N,N-methylene-bis-acrylamide (MBA)as crosslinking agent.Scanning electron microscopy (SEM)and dynamic light scattering were utilized to analyze the surface morphologies and particle sizes of microgels.The reversible phase inversion process of microgels was studied,and the trapping properties of microgel emulsion for CO2were researched by capture and release tests at variable temperature.The results showed microgel was better responded the temperature.The regular spherical particles of microgel had uniform distribution and good reversible stability.Reversible capture and release of CO2 by poly(NIPAM-co-DMAPMA)microgel could be achieved when the temperature was altered.
