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 CO2 were 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.
