HEAT-RESPONSIVE POLYMER GEL FILM

摘要

Disclosed is a heat-responsive polymer gel film which is characterized in that the difference of the total light transmittance before and after thermal stimulation is not less than 50%.  The heat-responsive polymer gel film changes in the degree of transparency by thermal stimulation.  The temperature of the thermal stimulation is preferably not less than room temperature but not more than 100°C.  The heat-responsive polymer gel film preferably contains not less than 10% by mass of water, and a material constituting the heat-responsive polymer gel film preferably contains a rotaxane structure.
