▎ 摘　　要

NOVELTY - Preparation of multifunctional nanocomposite coating film involves (i) adding water to graphene quantum dots and uniformly dispersing to obtain a component (a), (ii) adding water to nanosilica and uniformly dispersing to obtain a component (b), (iii) mixing the component (a) and component (b) and ultrasonically-dispersing to obtain a component (c), (iv) coating the component (c) onto a glass as a substrate by dipping and pulling method to form a coating film, and drying, (v) soaking the dried coating film in n-hexane solution of trimethoxy(1H,1H,2H,2H-heptadecafluorodecyl)silane, and (vi) drying the soaked coating film. USE - Preparation of multifunctional nanocomposite coating film used in new energy and self-cleaning material, for solar cell, optoelectronic device and biomedicine application. ADVANTAGE - The method provides multifunctional nanocomposite coating film having high light transmittance and adhesiveness, and good hydrophobicity and mechanical stability. The method is simple and environmentally-friendly.
