摘要 采用水溶液聚合法合成了N,N-二甲基丙烯酰胺(DMAM)与丙烯酸(AA)的共聚物[P(DMAM-coAA)]水凝胶,研究了温度、Na Cl浓度、p H值对水凝胶溶胀行为的影响,以及该水凝胶的溶胀与消胀动力学。结果表明:P(DMAM-co-AA)水凝胶的吸水能力随温度和Na Cl浓度升高而下降,在中性条件下的吸水能力较弱,在酸性和碱性条件下吸水能力较强,其溶胀和消胀速率随溶胀时间和消胀时间延长而逐渐降低,约10 h达到平衡状态。 Coploymer hydrogel of N, N-dimethyl acrylamide and acrylic acid was synthesized via aqueous solution polymerization. The influences of temperature,NaCl concentration and pH value on the swelling behavior of the copolymer hydrogel were studied. And the swelling and deswelling kinetics of the copolymer hydrogel was also researched. The results show that the water-absorption capacity of the copolymer hydrogel is decreased with the increase in the temperature and the NaCl concentration. The copolymer hydrogel has a low water-absorption capacity under the neutral conditions,while the water-absorption capacity is improved in the acid or alkaline environment. The swelling rate and deswelling rate are gradually decreased with time,and the equilibrium state is obtained after 10 hours or so.
