摘要：

gamma-ray irradiation of N-isopropylacrylnmide (NIPAAm) monomer solution resulted in the formation of the opaque poly(N-isopropylacrylamide) (PNIPPAAm) gel having a microporous structure. The thermo-responsive properties of the microporous gel were the same as that of a homogeneous gel prepared by conventional methods. The gel swelled below and shrunk above the lower critical solution temperature (LCST) (33 degrees C). The rapid and reversible volume change was observed by changing temperature.
