Embodiment 1
[0024] In the first step, take 120mL of absolute ethanol in a beaker, add 8mL of butyl titanate drop by drop while ultrasonicating, mix and prepare a butyl titanate solution, and then soak 1.6227g of pure cotton fabric into the prepared solution for 24 hours ;
[0025] In the second step, immerse the pure cotton fabric treated in the first step in 20mL of absolute ethanol, add 20mL of deionized water drop by drop while ultrasonicating, and hydrolyze for 0.5h;
[0026] In the third step, the hydrolyzed mixed solution in the second step is placed in a polytetrafluoroethylene autoclave, subjected to hydrothermal treatment at 120° C. for 8 hours, and cooled at room temperature;
[0027] In the fourth step, pour the mixed solution after the hydrothermal treatment in the third step into a beaker, ultrasonicate for 1 minute, and then wash the fabric with deionized water three times to remove the substances that are not firmly bonded to the surface, and dry;
[0028] In the fifth ste...
