Wave-to-heat conversion structure and application thereof

A wave-to-heat conversion structure being a loose tissue formed by a plurality of intersecting and hooking fibrous structures, the loose tissue retaining a dendritic structure of the fibrous structure, and a plurality of micro-gaps formed and existing between the fibrous structures,

• wherein the fibrous structure comprises expanded graphite which is a first multilayer graphene structure having 50-1000 layers,
• the wave-to-heat conversion structure further comprises a heat conductive layer, the fibrous structures are arranged on a surface of the heat conductive layer, the heat conductive layer is configured to conduct heat,
• the heat conductive layer is a composite material consisting of the expanded graphite, a second multilayer graphene structure having 50-250 layers, and carbon nanotubes,
• the second multilayer graphene structure and the carbon nanotubes are evenly distributed in the expanded graphite to form a three-dimensional thermally conductive network,
• a mass percent of the expanded graphite in the heat conductive layer is greater than or equal to 70% and less than 100%, a mass percent of the second multilayer graphene structure in the heat conductive layer is larger than 0 and less than 30%, and a mass percent of the carbon nanotubes is larger than 0 and less than 30%.
