Title:
PREPARATION METHOD FOR CARBON NANO TUBE/POLYACRYLIC ACID HYDROGEL, AND PRODUCT AND APPLICATION OF CARBON NANO TUBE/POLYACRYLIC ACID HYDROGEL
Document Type and Number:
WIPO Patent Application WO/2023/108868
Kind Code:
A1
Abstract:
The present invention relates to the technical field of solar seawater desalination, and disclosed are a preparation method for carbon nano tube/polyacrylic acid hydrogel, and a product and application of carbon nano tube/polyacrylic acid hydrogel. The preparation method comprises the following steps: oxidizing a carbon nano tube into a carboxylated carbon nano tube, and then performing in-situ polymerization with acrylic acid, sodium hydroxide, ammonium persulfate, triethanolamine, and N,N'-methylenebisacrylamide to obtain carbon nano tube/polyacrylic acid hydrogel. The hydrogel is of a uniform porous structure, and facilitates rapid transmission and supply of water; the carbon nano tubes in the hydrogel are of an array structure, and can fully receive solar energy and generate high-efficiency photothermal conversion; a solar-driven carbon nano tube/polyacrylic acid hydrogel photothermal conversion steam generator is formed by tightly attaching the carbon nano tube/polyacrylic acid hydrogel to a polyurethane sponge base, is used for solar seawater desalination, can further improve the evaporation rate and evaporation efficiency of solar seawater desalination, and has the advantages of being energy-saving, environmentally-friendly, simple, practicable, and the like.
