Embodiment 1

[0056] (1) Take 0.5g of γ-mercaptopropyltrimethoxysilane in 200mL of water, stir mechanically at 200 rpm until the solution is clear and transparent, then adjust the pH to about 9 with ammonia water, continue to stir mechanically for 12 hours, and the solution changes from a transparent solution to a Milky white solution, then centrifuge at 3000 rpm to remove the supernatant, add deionized water to wash 5 times, freeze in liquid nitrogen at -196°C, dry under 10 Pa vacuum condition for 24 h to obtain white silicone pellet powder, and set aside;

[0057] (2) Weigh 0.5 g of silicone pellets, disperse them uniformly in 50 mL of water, and then add 100 μL of 0.25 mol L -1 The solution was ultrasonically reacted until the color no longer changed, then centrifuged at 3000 rpm to remove the supernatant, and dried under 10 Pa vacuum for 12 h to obtain gold-complexed organosilicon pellet powder;

[0058] (3) Put the gold-complexed silicone pellet powder in a quartz boat, put it into a t...

Abstract

The invention relates to a preparation method of a GSP film material for solar photo-thermal steam conversion in the technical field of energy materials. The method comprises the steps: dispersing organosilicon powder in water, adding a chloroauric acid solution, and carrying out ultrasonic reaction to obtain gold complex organosilicon spheres; carrying out liquid nitrogen freezing, drying in vacuum to obtain gold complex organosilicon sphere powder; carrying out a reaction on the gold complex organosilicon sphere powder under the protection of protective gas; calcining at the temperature of 500 DEG C to 1000 DEG C, to obtain gold nanoparticle doped carbonized organosilicon sphere powder; dispersing the gold nanoparticle doped carbonized organosilicon sphere powder into water; dropwise coating on fiber filter paper; and carrying out vacuum filtration, to obtain the GSP film material. The surface plasmon polariton effect generated by the prepared GSP film material under the irradiationof sunlight enables the sunlight to be fully absorbed; the GSP film material has a better heat conduction effect due to the low heat conduction coefficient and the high heat diffusion coefficient of the film material, the heat loss in the heat transfer process is reduced, and the GSP film material has high water evaporation rate.

Description

technical field [0001] The invention relates to the technical field of energy materials, in particular to a preparation method of a GSP film material applied to solar photothermal steam conversion. Background technique [0002] Water resources are related to human health and future, but with the development of economy and industry, water pollution and water resource shortages are becoming more and more serious. If the current situation continues, more than two-thirds of the population on the earth will face water resource problems in the future. Therefore, the reuse of wastewater treatment or the desalination of seawater for human use has become a research hotspot all the time. As a renewable, clean and pollution-free resource, solar energy has always been concerned by human beings. It is widely used in wastewater treatment and seawater desalination, sterilization and catalysis, and has a very broad application prospect. [0003] Despite this, the technology applied to sola...
