Fabric wet power generation material based on molybdenum disulfide, and preparation method and use therefor

A preparation method of a fabric wet power generation material based on molybdenum disulfide, characterizing in comprising the following steps:

• (1) washing and drying the silk fabric, and carbonizing it in an argon atmosphere at a temperature of 900-1500° C. for 90-180 minutes;
• dissolving anhydrous sodium molybdate in deionized water, adding L-cysteine powder into the anhydrous sodium molybdate solution according to a molar ratio of anhydrous sodium molybdate to L-cysteine of 1:2.5-1:3.0, and fully dissolving to obtain a mixed solution;
• adding the carbonized silk fabric into the mixed solution, stirring for 1-2 h, then placing the silk fabric in a high-pressure reactor, reacting for 10-24 h at a temperature of 200-250° C. and a pressure of 1-4 MPa, and washing and drying to obtain an MoS2 in-situ grown carbonized fabric;
• (2) adding bulk MoS2 to the n-butyllithium solution according to a mass ratio of 15:1-18:1, and dealing with water bath exfoliation treatment for 10-15 h under an argon atmosphere at a temperature of 60-80° C., then performing centrifugal separation;
• washing with n-hexane and dispersing the washed powder in water at a concentration of 0.5-5 mg/mL, performing ultrasonic dispersion treatment for 1-2 h, and then performing centrifugal separation at a rotational speed of 2000-3000 r/min to obtain a MoS2 sheet layer material, which is then configured to be an MoS2 aqueous dispersion of 0.01-0 03 M;
• placing the cellulose fiber fabric in the MoS2 aqueous dispersion for 10-60 min, keeping the liquid rate at 80-120% by rolling, baking for 3-15 min at a temperature of 130-150° C., spin-coating a polyacrylamide solution at a rotational speed of 2000-5000 r/min, and drying to obtain a MoS2-based conductive cellulose fiber fabric;
• (3) superposing the MoS2 in-situ grown carbonized fabric obtained in step (1) and the MoS2-based conductive cellulose fiber fabric obtained in step (2) to obtain a fabric wet power generation material based on molybdenum disulfide.
