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.
