Document Type and Number:
WIPO Patent Application WO/2019/194022
Kind Code:
A1
Abstract:
Provided is a heat storage material which is formed of a temperature-sensitive polymer gel comprising: a temperature-sensitive polymer; water; and a solvent selected from the group consisting of organic solvents and mixtures thereof, wherein the heat storage material reversibly switches between hydrophilicity and hydrophobicity at a lower critical solution temperature, and during the switching process, the solvent contained in the temperature-sensitive polymer gel maintains a liquid state.
