▎ 摘  要

NOVELTY - A face mask consists of a mask component having a margin (38), an inner layer (32), which is a breathable material having interstitial spaces, an inner surface, and an outer surface (46), and a graphene layer abutting the outer surface, which is functionalized with several silver nanoparticles, for providing a functionalized graphene layer, and straps attached to the mask component proximate the margin for releasably retaining the mask on a user's face. USE - Face mask is used for reducing pathogens in air inhaled/exhaled by user (claimed). The pathogens are bacteria, fungus, and virus. ADVANTAGE - The face mask has excellent protection performance against airborne microbes, with respect to user, without restricting air flow to the user, and removability/replaceability of mask insert, and is economical. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: insert (30) for face mask, which consists of the graphene layer functionalized with silver nanoparticles; and method for reducing pathogens in air inhaled/exhaled by user, which involves providing the face mask and locating the face mask on the face of user, such that mouth and nostrils of the user are covered for breathing through the face mask. DESCRIPTION OF DRAWING(S) - The drawing shows the cross-sectional view of mask. 30Insert 32Inner layer 34Outer layer 38Margin 40Pocket 46Outer surface 48Inner surface
