▎ 摘　　要

NOVELTY - A face mask comprises mask component for covering at least the wearers mouth and nose and having an inner side facing towards the wearer, and fastener to hold the mask in place on the wearers face and comprising a portion which engages the mask component and portion which engages with the wearer. The mask component comprises an air-permeable outer layer, an inner layer located on an inner side of the mask component, and graphene layer arranged in the mask component. The graphene layer comprises discrete single-layer or few-layer graphene sheets chosen from pristine graphene, graphene oxide, reduced graphene oxide, graphene fluoride, graphene chloride, graphene bromide, graphene iodide, hydrogenated graphene, nitrogenated graphene, doped graphene, and/or chemically functionalized graphene. The fastener connects the mask component to the wearer. USE - Face mask e.g. surgical mask. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for filtration material, which comprises a layer of woven or nonwoven fabric comprising two primary surfaces and graphene layer deposited on at least one of the two primary surfaces or embedded in the layer of woven or nonwoven fabric.
