Abstract: A composite material is applicable for photothermal energy conversion and thermal energy storage form-stable phase change. The composite material includes a supporting material and an organic phase-change material. The mass ratio of the supporting material to the organic phase change material is 3:7 to 1:9. The supporting material is lamellar, and the organic phase change material is evenly filled between supporting material layers to form a layered stacked structure. The supporting material is a nanosheet of Ti2C, Ti3C2, Ti3CN, V2C, Nb2C, TiNBC, Nb4C3, TA4C3, (Ti0.5Nb0.5)2C, or (V0.5Cr0.5)3C2. The organic phase-change material is paraffin, fatty acid, fatty acid ester or alcohol compound.

Abstract: The present invention relates to the technical field of new materials, and relates to a thermal conduction enhanced organic composite shape-stabilized phase change material and a preparation method thereof. A thermal conduction enhanced organic composite shape-stabilized phase change material, which is composed of a coordination crosslinked network polymer, an organic solid-liquid phase change material and a thermal conduction enhancer, the mass percent are as follows: coordination crosslinked network polymer 1-50%, organic solid-liquid phase change material 40-98.9%, and thermal conduction enhancer 0.1-10%, the coordination crosslinked network polymer being formed by complexing of polymer compound with metal ions. The invention has simple synthesis process and convenient applications, the material having large enthalpy of phase change, excellent shape stabilizing effect, while the phenomenon of liquid leakage will not occur during operation. The material has broad application prospects in the field of thermal energy storage and management.
