Title:
MULTI-DIMENSIONAL ASSEMBLED PHOTOTHERMAL PHASE CHANGE MATERIAL, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/097744
Kind Code:
A1
Abstract:
A multi-dimensional assembled photothermal phase change material, comprises a one-dimensional carbon substrate, a multi-level structure carbide, and a phase change energy storage material adsorbed in the framework material. The photothermal conversion phase change material effectively solves the limitation of single waste heat energy storage of a traditional organic phase change material. Moreover, the unique multi-dimensional assembly structure effectively increases the optical path length and reduces the optical loss of a system. The heat absorption characteristic of the phase change material enables the phase change material to effectively reduce the thermal loss of the system while storing energy, and further enhances the photothermal conversion efficiency of the material. The phase change enthalpy value of the composite phase change material is increased by regulating the non-bonded weak interaction between a C-H bond of a non-polar organic phase change core material and a delocalized π electron of a carbon carrier, and the phase change energy storage efficiency is significantly improved. The composite phase change material has remarkable advantages of high photothermal conversion efficiency, high energy storage density, and high cycle stability, and has a wide application prospect.
