摘　　要：利用化学交联法,以过硫酸胺(APS)为引发剂,以N,N′-亚甲基双丙烯酰胺(BIS)为交联剂,制备丙烯酰胺(AM)、丙烯酸(AA)共聚凝胶,初步探索凝胶在NaCl溶液中直流电场作用下的溶胀、弯曲行为.讨论了电压和电解质溶液浓度对凝胶弯曲行为的影响,凝胶在蒸馏水和盐水中的溶胀率,以及丙烯酸加入质量对P(AA-AM)凝胶溶胀率的影响,凝胶的溶胀率在pH值7左右出现最大值.The P（AA-AM） hydrogels were synthesized by radical polymerization, with anmoium persulfate（APS） as an initiator, N,N＇-Methylenebis acrylamide（BIS） as cross linker. The bending and swelling behavior of hydrogels were investigated in the DC electric field. The effects of voltage and electrolyte concentration on bending behavior, and swelling ratio in pure water and brine were studied. The amount of AA in P（AA-AM） hydrogels on swelling ratio were discussed, the swelling ratio appeared the maximal value when the pH was about 7.
