| Outline of Final Research Achievements |
The purpose of this study is to synthesize the temperature-responsive membrane by covering the temperature-responsive polymer (poly(N-isopropylacrylamide), PNIPAM) onto the inorganic porous membrane. The membrane covered with N, N'-methylenebisacrylamide-crosslinked PNIPAM was also prepared in order to change the transition temperature. When the methyl orange (MO) was used as a guest molecule for the membrane permeation experiment, it was found that the permeation rate of MO molecule above the transition temperature was much faster than that below the transition temperature. Moreover, when the amount of added BIS was increased, it was clarified that the MO molecule did not pass through the membrane below the transition temperature at all. In this way, we succeeded that the synthesis of temperature-responsive membrane in which the permeation rate of molecule changed by changing the solution temperature.
