▎ 摘　　要

NOVELTY - Preparing thermoplastic polyethylene glycol-based phase change energy storage material involves dissolving high molecular weight mono-acrylic esterified polyethylene glycol, initiator, and nano heat conducting filler dispersion in the low molecular weight mono-acrylic acid esterified polyethylene glycol, stirring uniformly to obtain the precursor, the precursor curing and forming to obtain the thermoplastic polyethylene glycol phase change energy storage material. The curing method is photo-curing or thermally curing; the average molecular weight of the high molecular weight mono-acrylic esterified polyethylene glycol is 1000 to 20000. The average molecular weight of the low molecular weight mono-acrylic acid esterified polyethylene glycol is 200 to 1000. USE - Method for preparing thermoplastic polyethylene glycol-based phase change energy storage material in the field of heat energy storage (claimed). ADVANTAGE - The method enables to prepare thermoplastic polyethylene glycol-based phase change energy storage material is widely applied to the heat energy storage field. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a thermoplastic polyethylene glycol-based phase change energy storage material prepared by the preparation method.
