▎ 摘　　要

NOVELTY - Water-limiting type high-efficiency photo-thermal evaporation material,comprises nano-pore photo-thermal conversion material layer and hydrophilic material filled in nano-pore so as to form high-water-absorbing confinement evaporation structure. USE - Limited-area water type efficient photothermal evaporation material. ADVANTAGE - The nanopore photo-thermal conversion material layer is constructed, and the hydrophilic material is filled in nanopores to form high water absorption limited evaporation structure, so that the evaporation form of water molecules in limited space is changed, the evaporation enthalpy is reduced, evaporation rate and the photo-thermal conversion efficiency are obviously improved, the solar energy conversion capability is greatly improved, manufacturing cost and the energy consumption cost are saved, and nanopore photo-thermal conversion material layer is suitable for micro devices and has higher universality. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for water-limiting type high-efficiency photo-thermal evaporation device,where it is prepared by using water-limiting type high-efficiency photo-thermal evaporation material.
