NOVELTY - Self-cleaning cotton fabric with silver sulfide quantum dot composite graphene and titanium dioxide involves mixing graphene oxide with water under ultrasonic stirring to obtain a mixture, placing pretreated cotton fabric into the mixture for treatment, removing cotton fabric and rinse with deionized water, then immersing the cotton fabric in the reducing solution for reduction, rinsing with deionized water and drying, loading titanium dioxide under stirring, adding tetrabutyl titanate dropwise to the mixed solution of ethanol and acetic acid, and continue to stirring after the dropwise addition, adding acetic acid to the ultrapure water, adding the resulting mixed drops to the ultrapure water with stirring, and aging to obtain the treatment liquid. The cotton fabric treated is immersed into the treatment solution, performed two dips and two rolls, washed in deionized water, dehydrateed and dried, supported silver sulfide quantum dots. USE - Method for self-cleaning cotton fabric with silver sulfide quantum dot composite graphene and titanium dioxide. ADVANTAGE - The method enables to self-clean cotton fabric with silver sulfide quantum dot composite graphene and titanium dioxide improves self-cleaning effect. DETAILED DESCRIPTION - Self-cleaning cotton fabric with silver sulfide quantum dot composite graphene and titanium dioxide involves mixing graphene oxide with water under ultrasonic stirring to obtain a mixture, placing pretreated cotton fabric into the mixture for treatment, removing cotton fabric and rinse with deionized water, then immersing the cotton fabric in the reducing solution for reduction, rinsing with deionized water and drying, loading titanium dioxide under stirring, adding tetrabutyl titanate dropwise to the mixed solution of ethanol and acetic acid, and continue to stirring after the dropwise addition, adding acetic acid to the ultrapure water, adding the resulting mixed drops to the ultrapure water with stirring, and aging to obtain the treatment liquid. The cotton fabric treated is immersed into the treatment solution, performed two dips and two rolls, washed in deionized water, dehydrateed and dried, supported silver sulfide quantum dots. The cotton fabric obtained is immersed in a silver nitrate solution for treatment, dehydrated and dried, and then rinsed with deionized water, immersed in an aqueous solution of sodium sulfide and then rinsed with deionized water and dried.
