Abstract

The invention belongs to the field of environmental energy applications, and relates to a high-efficiency photothermal conversion material and its preparation, in particular to a high-efficiency photothermal conversion material with a roll-like structure with a macroscopically controllable morphology, its preparation method and application. The photothermal material is a three-dimensional photothermal material obtained by modifying and curling. The photothermal conversion roll is composed of a substrate with a void structure and a functional photothermal polymer, and has a macroscopic cone-shaped or cylindrical hollow structure. The photothermal roll of the present invention greatly promotes the evaporation efficiency of water.

Description

A high-efficiency photothermal conversion material with a roll-shaped structure and a preparation method thereof application technical field The invention belongs to the application field of environmental energy, relate to efficient photothermal conversion material and preparation thereof, specifically a A high-efficiency photothermal conversion material with a roll-like structure with a macroscopic controllable morphology, and a preparation method and application thereof. Background technique The light-driven water evaporation process has broad application prospects in the field of preparing clean fresh water, and it is significant in terms of resource shortages. However, under natural evaporation conditions, the utilization rate of light is low and the actual evaporation rate is slow, It is difficult to meet the needs of large-scale freshwater production. Therefore, in practical life, the preparation of clean fresh water based on light-driven evaporation is often...
