▎ 摘　　要

NOVELTY - A graphene oxide-based anti-fog haze filter mask comprises self-assembled porous sponge-like three-dimensional graphene oxide and a pore size of 10 nm-1.5 mu m and a specific surface area of 100-2000 m2/g. USE - Graphene oxide-based anti-fog haze filter mask is used for PM 2.5 and other air pollutants, dyes and oil adsorption (all claimed). ADVANTAGE - The graphene oxide-based anti-fog haze filter mask has excellent mechanical strength, high specific surface area, adsorption effect and antibacterial property, and can be economically prepared by simple process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene oxide-based anti-fog haze filter mask, which involves selecting different mesh number graphite powder as raw materials, preparing graphene oxide of different sizes by dispersing raw material in water, adding crosslinking agent, performing hydrothermal reaction and drying.
