NOVELTY - The utility model claims a graphene haze prevention mask; the main body of the mask haze is divided into five layers, from inside to outside in turn is face adhering layer, big sheet graphene oxide, structure reinforcing layer, small sheet graphene oxide layer and an outer surface layer; the large sheet transverse size of the graphene oxide greater than 5 microns, said small sheet transverse size of the oxide graphene is not larger than 5 microns, functionalized graphene with a large number of surface functional groups and large specific surface area is used as mask filter layer has strong adsorption capacity, wherein small sheet graphene oxide layer outside, for the large particle dust preliminary filtering air, big sheet graphene oxide layer, for further filtering the small particle dust in the air, two-layer filtering layer coordinated with each other, greatly enhances the anti-haze capability of the mask.
