Summary: | Stimule-sensitive hydrogels which respond to changes in various environmental conditions such as temperature, pH, and electric field were synthesized by means of gamma -ray polymerization of comonomers. The comonomers consisted of N-isopropylacrylamide, acrylic acid or methacrylic acid and a crosslinker such as diethylene glycol dimethacrylate and polyethylene glycol dimethacrylate. The effects of comonomer composition, alkali treatment of the copolymer and crosslinking on the temperature depending swelling and the shrinkage under electric field were studied comparatively. It was observed that the gels showed a maximum responsiveness at a certain composition of acidic monomer and the alkali treatment enlarged such a maximum composition range. The kind of crosslinkers affected also on the stimule-responsiveness. |
