摘要
采用水溶液聚合法制备了一系列电场敏感性水凝胶,对非接触直流电场作用下单体配比、单体质量分数、交联剂用量、引发剂用量等对水凝胶树脂最大弯曲偏转度的影响进行了研究.结果表明,当单体配比为m(NIPAAm)∶m(DMAEMA)=2∶5,单体质量分数为35%,交联剂用量为占单体质量的0.1%,引发剂用量为单体质量的1.4%(其中m(过硫酸铵)∶m(亚硫酸氢钠)=4∶3)时,合成的一系列Poly(NIPAAm-co-DMAEMA)水凝胶在ω(NaCl)=0.9%溶液中有最佳的最大弯曲偏转角,即130°,且都弯向正极;NIPAAm均聚物在非接触电场下无弯曲现象;常温下合成的DMAEMA均聚物电敏感不明显.
A series of electric field sensitive gels were prepared by free-radical polymerization. The influences of the concentration of monomers, the mass ration of monomers, the amount of initiator and crosslinking agent on the maximum bending angle of the hydrogels under the non-contacting DC electric field were studied. It was found that the a best maximum bending angle of the hydrogel was 130° in the concentration of 0. 9% NaC1 when the mass ration of monomers, the concentration of monomers, the amount of initiator and crosslinking agent respectively were m （NIPAAm） ： m （DMAEMA） = 2： 5, 35 %, 0. 1%, and 1.4% （m （APS） ： m （SBS） = 4 ： 3 ） relative to the mass of monomers, and the hydrogels bended toward to cathod. There was no bending phenomenon under the non-contacting DC electric field in the homopolymer of NIPAAm. The electric sensitivity of DMAEMA homopolymer, prepared at normal temperature, was not obvious.
