Abstract

The invention relates to a preparation method of a light absorption-water delivery and heat insulation integrated photo-thermal evaporation material, and the light absorption-water delivery and heat insulation integrated photo-thermal evaporation material obtained by the preparation method. The invention also relates to application of the light absorption-water delivery and heat insulation integrated photo-thermal evaporation material in absorbing sunlight and generating heat to accelerate water evaporation. The light absorption-water delivery and heat insulation integrated photo-thermal evaporation material prepared by the method can solve the heat loss of water in the transportation process, so that the photo-thermal conversion rate is increased. The photo-thermal evaporation material provided by the invention can also solve the technical problem that: the stability of a device is reduced in that a light absorber is separated from a heat insulator.

Description

technical field [0001] The invention relates to the technical field of photothermal materials, in particular to a photothermal material that effectively utilizes solar energy to accelerate water evaporation, which can be applied to seawater desalination, sewage treatment and the like. Background technique [0002] With the development of society and the further understanding of the importance of environmental protection awareness in China, my country has gradually attached importance to the development of solar energy resources to improve the level of environmental protection in society. The use of solar energy to drive water evaporation is a typical example of the application of photothermal conversion in solar energy. Its conversion efficiency is relatively high, and it has the potential of industrial production of clean water. [0003] Solar energy-driven water evaporation technology is generally divided into two types. One way to use solar energy is to convert solar ene...
