THERMOTROPIC COMPOSITION CONTROLLABLE PHASE TRANSITION TEMPERATURE AND FREEZING POINT FOR SMART WINDOW

摘要

The present invention relates to a thermotropic composition for a smart window capable of controlling a phase transition temperature and a freezing point, and more specifically, in a thermotropic composition for a smart window formed by mixing and reacting a solvent, NIPAm, MBAAm, APS and TEMED, NIPMAm In addition, by using P (NIPAm-co-NIPMAm) formed by copolymerization, and by using a solvent mixture consisting of water and glycol as a solvent, LCST can be freely controlled and its utility and energy saving efficiency can be improved. In addition, it relates to a thermotropic composition for a smart window capable of controlling a phase transition temperature and a freezing point, which enables the adjustment of the freezing point to improve its use efficiency even in cold winter.
