Problems solved by technology

[0004] At present, the light absorber material used in research directly floats on the surface of seawater, but because the light absorber is in direct contact with seawater, there is no heat insulation layer, a large part of heat energy is directly transmitted through seawater, and it cannot achieve the purpose of local heating, resulting in Low light-to-heat conversion efficiency

Abstract

The invention discloses a functional nonwoven sea water desalination material and a preparation method and application thereof. The sea water desalination material uses non-woven as a basis material, and a carbon material loaded on the surface as a light absorber. The functional nonwoven sea water desalination material internally includes short staple which has a core absorption effect on sea water and provides a water transport corridor, and the pore structure of the material is beneficial to passing of water vapor. The sea water desalination material has a good thermal insulation performance to avoid the loss of solar energy, and as the light absorber, the material has a high utilization rate of solar energy so that the water vapor producing efficiency is high; the material is durable and convenient to transport, and the preparation method has low costs and a simple process.

Description

technical field [0001] The invention belongs to the field of light-to-heat conversion, and relates to a functional material, in particular to a functionalized nonwoven seawater desalination material and its preparation method and application. Background technique [0002] The scarcity of fresh water resources has become one of the global challenges of this era. Using solar energy to directly evaporate seawater is an effective method for seawater desalination and desalination, and this method does not require additional energy supply, meets the requirements of energy saving, emission reduction, and sustainable development, and is especially suitable for some remote areas with backward infrastructure. [0003] The emissivity and refractive index of seawater are relatively high, so it cannot make good use of solar energy to generate water vapor. In order to improve the utilization rate of solar energy and the production efficiency of water vapor, researchers use materials with...
