▎ 摘　　要

NOVELTY - Composite photo-thermal fabric with high evaporation performance, comprises a photothermal layer and a base layer adjacent thereto; where the photothermal layer is a carbon-based polymer porous film including polymers and carbon-based nanoparticles dispersed in it; the thickness of the photothermal layer is 10-100 µm, and the average pore size is 1-10 µm; the porosity is 65-95%; the polymer is a hydrophilic polymer or a hydrophobic polymer; and the base layer is a hydrophilic fabric. USE - The composite photo-thermal fabric is useful for seawater desalination and waste water treatment based on solar steam generation in environment energy application technology field. ADVANTAGE - The composite photo-thermal fabric has high evaporation performance, excellent mechanical performance, good stability and high efficiency of light steam conversion ability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the composite photo-thermal fabric with high evaporation performance, comprising coating the carbon-based nanoparticle/polymer mixed solution on the hydrophilic fabric, forming the carbon-based polymer porous film by the water drop template method and obtaining a composite photothermal fabric with high evaporation performance, where the carbon-based nanoparticle/polymer mixed solution is mainly composed of the carbon-based nanoparticle, the polymer and a solvent. DESCRIPTION OF DRAWING(S) - The drawing shows a preparation flow of the composite photo-thermal fabric (Drawing includes non-English language text).
