| 摘 要： | 以2-丙烯酰胺基-2-甲基丙磺酸(AMPS)和甲基丙烯酸N,N-二甲氨基乙酯(DMAEMA)为单体,N,N′-亚甲基双丙烯酰胺为交联剂,过硫酸铵和亚硫酸氢钠为氧化还原引发剂,采用水溶液聚合法制备了AMPS/DMAEMA水凝胶,考察了样品水凝胶在外加直流电场刺激下的消溶胀动力学和弯曲行为.结果表明,DMAEMA单体含量和施加电压大小对水凝胶的电敏感性能有着显著影响.用一级动力学方程能够较好地描述水凝胶在接触电压刺激下的消溶胀过程.在非接触电压刺激下,单体摩尔比,n(AMPS):n(DMAEMA)=9:1的水凝胶向负极弯曲;单体摩尔比n(AMPS):n(DMAEMA)=5:5的水凝胶向正极弯曲;单体摩尔比n(AMPS):n(DMAEMA)=7:3的水凝胶随着非接触电压的增大,出现先向负极弯曲,后向正极弯曲的现象.

| Abstract: | 2-acrylamido-2-methylpropane sulfonic acid/2-(dimethylamino)ethyl methacrylate(AMPS/DMAEMA) hydrogels were prepared by free radical copolymerization in aqueous solution in the presence of N,N methylene bis(acrylamide)(MBAAm) as crosslink agent,ammonium persulfate and sodium bisulfite as redox initiator.Deswelling kinetics and bending behaviors of the sample hydrogels under electric stimulus were illustrated.It was found that monomer amount of DMAEMA and electric field had a favorable impact on electric sens... |
