Title
(EN) ANTIVIRAL ELEMENT AND PERSONNEL PROTECTION EQUIPMENT CONTAINING SAME
(FR) ÉLÉMENT ANTIVIRAL ET ÉQUIPEMENT DE PROTECTION DU PERSONNEL LE CONTENANT
Abstract
(EN) Provided is graphene-based personnel protection equipment (PPE) product, comprising: (a) a fabric, clothing, face shield, face mask, or glove body configured to support graphene sheets; and (b) graphene sheets deposited on a surface of the body or at least partially embedded in the body, wherein the graphene sheets comprise a plurality of discrete single-layer or few-layer graphene sheets selected from pristine graphene, graphene oxide, reduced graphene oxide, graphene fluoride, graphene chloride, graphene bromide, graphene iodide, hydrogenated graphene, nitrogenated graphene, doped graphene, chemically functionalized graphene, or a combination thereof. Preferably, surfaces of graphene sheets carry an anti-microbial compound, preferably in the form of a nanoparticle, nano-wire, or nano-coating.
(FR) L'invention concerne un produit d'équipement de protection du personnel (PPE) à base de graphène, comportant: (a) un tissu, un vêtement, un écran facial, un masque facial ou un corps de gant configuré pour supporter des feuilles de graphène; et (b) des feuilles de graphène déposées sur une surface du corps ou au moins partiellement incorporés dans le corps, les feuilles de graphène comportant une pluralité de feuilles de graphène discrètes monocouches ou à faible nombre de couches sélectionnées parmi du graphène intact, de l'oxyde de graphène, de l'oxyde de graphène réduit, du fluorure de graphène, du chlorure de graphène, du bromure de graphène, de l'iodure de graphène, du graphène hydrogéné, du graphène azoté, du graphène dopé, du graphène chimiquement fonctionnalisé, ou une combinaison de ceux-ci. De préférence, les surfaces des feuilles de graphène portent un composé antimicrobien, de préférence sous la forme d'une nanoparticule, d'un nanofil ou d'un nano-revêtement.
