▎ 摘  要

NOVELTY - Super-hydrophilic passive self-cleaning coating comprises 19-32 pts. wt. nano titanium dioxide, 12-23 pts. wt. nano silicon dioxide, 4-10 pts. wt. graphene oxide, 6-15 pts. wt. dispersant, 39-68 pts. wt. deionized water, 4-10 pts. wt. film-forming agent and 1-3 pts. wt. inhibitor. USE - Used as Super-hydrophilic passive self-cleaning coating. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for: (1) preparing the coating, comprising (1) adding nano titanium dioxide, nano silicon dioxide, graphene oxide and dispersant to absolute ethanol, magnetically stirring for 60 minutes, and obtaining black solution A, (2) mixing the film-forming agent and inhibitor, and magnetically stirring for 30 minutes to obtain solution B, (3) slowly adding solution B dropwise to solution A, and continuously stirring for 60 minutes to obtain sol C uniformly dispersed in black, and (4) heating the sol C at 50 degrees C and magnetically stirring for 60 minutes; and (2) preparing super-hydrophilic passive self-cleaning glass by using the super-hydrophilic passive self-cleaning coating, comprising (1) ultrasonically cleaning the glass substrate in isopropanol, absolute ethanol, and 30% hydrogen peroxide for 10 minutes, and drying at room temperature, (2) coating the super-hydrophilic passive self-cleaning coating on the glass substrate treated in the step (1) by spraying, placing it into ventilated drying box to dry, and (3) coating the super-hydrophilic passive self-cleaning coating again on the coating surface obtained in the step (2) by spraying method, placing in ventilated drying box to dry, and naturally cooling.
