P(AA-co-DMMC)水凝胶的γ辐射合成及pH响应行为

摘要

P(AA-co-DMMAC) hydrogels were synthesized by γ ray irradiation polymerization. The pH value responsive behaviors of hydrogels with different monomer ratios of (DMMC:AA) was studied. When the ratios were 1:3, 1:4, 1:5, and 1:6, the response behaviors was similar. At pH=7, the gels had large swelling properties, while at higher and lower pH values, the swelling was smaller. The situation was reversed when the monomer ratio was 1:2.%研究了DMMC:AA不同单体比值时辐射合成的P(AA-co-DMMC)水凝胶在不同pH值溶液中的行为，发现了该凝胶对pH值有响应，凝胶的响应还与其组成单体的比例有关，表现为当DMMC:AA为1:3、1:4、1:5、1:6时，其响应行为基本一致，在高和低pH值时，溶胀较小，在pH值等于7左右时溶胀较大，但当比例为1:2时，结果正好相反。
