NOVELTY - A graphene oxide-based environment-friendly antibacterial anti-haze mask comprises filter layer, mask belt and nose clip. The filter layer is rectangular or square-shaped nonwoven material comprising antibacterial layer and sol filter layer. The nonwoven material has moderate density and hydrophobic properties. The antibacterial layer is coated with graphene-tannic acid-nanosilver solution. USE - Graphene oxide-based environment-friendly antibacterial anti-haze mask. ADVANTAGE - The environment-friendly mask is nontoxic, eliminates odor, reduces flu respiratory resistance, avoids cross infection, and has antibacterial and anti-haze function, good air permeability, and simple preparation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of antibacterial anti-haze mask comprising: (A) cutting nonwoven material into 3 square or rectangular with same size, cutting sol filter layer with same size of nonwoven material, and spraying nonwoven material with graphene-tannic acid-nanosilver solution through air compressor; and (B) stacking with sol filter layer in certain order, placing nose clip on upper layer of filter at center position, placing mask belt on both side of nonwoven material, sewing, and bonding.
