1. A method for preparing a self-cleaning transparent thermal insulation nanocoating, the method comprising steps of:
(1) preparing an acidic aqueous solution, and adding polyoxyethylene dinonyl phenyl ether and graphene into the acidic aqueous solution;
(2) preparing a transparent composite nanosol by adding titanate, zinc alkoxide, ytterbium alkoxide, siloxane into the acid aqueous solution through sol-gel reaction;
(3) preparing a primary coating by spraying the transparent composite nanosol onto a glass surface; and
(4) spraying a dilute alkaline solution onto the primary coating to condense and crosslink components in the primary coating, so that the self-cleaning transparent thermal insulation nanocoating is in-situ generated on the glass surface.
