Abstract:
A process for preparing temp-sensitive porous aquagel of poly(N-isopropyl acrylamide includes such steps as dissolving N-isopropylacrylamide monomer and cross-linking agent in deionized water, adding CaCO3 and the aqueous liquid of trigger and promoter, loading in container, reaction to preparing aquagel, rinsing with deionized water, and rinsing with hydrochloric acid and deionized water. Its advantages are simple process, wide regulation range of pore diameters, and high transparency and elasticity.
