Abstract

The invention discloses a bio-based photothermal conversion material and a preparation method and application thereof, and belongs to the technical field of solar photothermal conversion. The invention aims to solve the technical problems of complex preparation method and high cost of an existing photothermal conversion material. The bio-based photothermal conversion material is prepared by the following steps of: ultrasonically treating shaddock peel with absolute ethyl alcohol, cleaning, drying, uniformly coating the surface with a dispersion liquid and curing. The preparation method specifically comprises the following steps of: 1, putting shaddock peel into absolute ethyl alcohol for ultrasonic treatment, then repeatedly washing with deionized water until the ethyl alcohol is completely removed, and then drying; 2, uniformly mixing acetone and absolute ethyl alcohol, then adding epoxy resin, a dispersing agent and carbon black, and sanding until the mixture is uniformly dispersed to obtain a dispersion liquid; and 3, uniformly coating the dispersion liquid obtained in the step 2 on the surface of the shaddock peel treated in the step 1, and curing to obtain the bio-based photothermal conversion material. The material is used for sewage treatment and seawater desalination.

Description

technical field

[0001] The invention belongs to the technical field of solar photothermal conversion; in particular, it relates to a bio-based photothermal conversion material and its preparation method and application. Background technique

[0002] In today's twenty-first century, the problem of lack of water resources is becoming more and more serious. 97% of the water resources on the earth are seawater. In order to increase the total amount of freshwater available to human beings, desalination of seawater has become a feasible method. However, the traditional desalination method is costly, long-term, generally effective, and consumes a lot of energy. For example, Distillation, reverse osmosis and other methods. Solar energy is a low-cost and renewable clean energy. Using photothermal conversion materials to convert solar energy into thermal energy to locally heat water bodies and obtain drinkable fresh water has a very promising application prospect.
