With N, N - and methyl double acrylamide as crosslinking agent, nitric acid as the initiator, cerium amine synthesized by solution polymerization PAAm - g - mpeg and PAAm mpeg/PVP copolymer - hydrogel. Research on the gel PH change sensitivity response. Research shows that PAAm - g - mpeg type water PAAm gel and mpeg/PVP type water - the gel, and joined the PVP hydrogel on PH change in response to proce a strong contrast. At the same time, because of acrylamide amide groups of copper (ii) can generate strong adhesion, and on the PH change also can proce certain response, so are studied. Research shows that PAAm mpeg/Cu g - type gel in alkaline solution, swelling performance, strong, PAAm Cu/mpeg/PVP - type gel in acidic solution, swelling performance.
