▎ 摘  要

NOVELTY - Graphene oxide photocatalytic cleansing mask comprises a film layer and a backing layer. The film layer is arranged on the backing layer. The film layer includes 10-30 wt.% graphene oxide titanium dioxide composite photocatalyst, 1-5 wt.% dispersant, 15-35 wt.% film-forming resin, 0.5-5 wt.% film-forming co-solvent, and water (remaining amount). USE - Used as graphene oxide photocatalytic cleansing mask. ADVANTAGE - The cleansing mask: utilizes the strong adsorption capacity of graphene oxide and the photocatalytic performance of titanium dioxide; quickly absorbs and decomposes oily secretions and oily cosmetics on the face; cleans the facial skin of the human body; has strong antibacterial properties; is suitable for facial skin acne, and users with acne; avoids the problem of cleansing the face of people with oiliness, makeup, and sensitive skin. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: 1 preparing graphene oxide titanium dioxide composite photocatalyst, comprising (i) mixing the deionized water and absolute ethyl alcohol to obtain mixed liquid one, dispersing the graphene oxide into the mixed liquid one, ultrasonically dissolving uniformly to obtain graphene oxide solution, (ii) adding the titanium-containing substance into the graphene oxide solution, uniformly stirring, orderly adding acid and deionized water, continuously uniformly stirring to obtain the precursor solution containing titanium element and graphene oxide, (iii) pouring the precursor solution into the reaction kettle, maintaining the first predetermined temperature, lasting for the first predetermined time, cooling the container, removing the supernatant, centrifuging, washing the precipitate for multiple times and drying to obtain the primary product, and (iv) grinding the primary product to obtain graphene oxide titanium dioxide composite photocatalyst; and 2 preparing the graphene oxide photocatalytic cleaning mask, comprising preparing the graphene oxide titanium dioxide composite photocatalyst, adding the graphene oxide titanium dioxide composite photocatalyst to deionized water, then adding the dispersant and uniformly stirring to obtain graphene oxide titanium dioxide composite photocatalyst solution, mixing the film-forming resin and the film-forming co-solvent, stirring until uniform to obtain film-forming solution, mixing and stirring the graphene oxide titanium dioxide composite photocatalyst solution and the film forming solution to obtain coating solution, attaching coating solution to the backing layer by coating, printing or dipping to obtain graphene oxide photocatalytic cleaning mask.
