▎ 摘　　要

NOVELTY - High-efficiency photo-thermal conversion material with polyhedron torsion structure comprise a polyhedral frame structure used as the unit cell. Multiple polyhedral frame structure unit cell models are arrayed 1-100 times along the XY axis line direction to obtain the array structure. One side end face is fixed along the axis direction of the array structure, and other end surface is twisted relative to the fixed end surface to obtain a polyhedron torsion structure. The polyhedral torsion structure adopts a ceramic matrix. The photothermal material slurry is dipped and coated on the degreased and sintered. The polyhedral twisted structure ceramic matrix after surface roughening treatment obtains a polyhedral twisted structure high-efficiency light-to-heat conversion material. USE - The material is useful in a light-to-heat supercapacitor and performance improvement effect of the photothermal supercapacitor under light conditions can be enhanced (claimed). ADVANTAGE - The high specific surface area hierarchical design of polyhedron torsion structure can obviously reduce the diffuse reflection of light on the material surface, allowing incident light to be reflected for many times in the structure, greatly improving the light absorption and light capture characteristics the material, obviously improving the surface balance temperature of the material under the illumination condition, Compared with the flat plate structure. The high-efficiency photo-thermal conversion material can greatly enhance the capacity lifting caused by photothermal effect as photothermally super capacitor electrode. The polyhedral frame structure has a minimum number of 2. The design optimization of the macrostructure can Obviously reduce the diffusion reflection of the light, the lifting material internal light reflection, realizing high-efficient absorption and capture of light. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of high-efficiency photothermal conversion material with polyhedron torsion structure.
