Title
(EN) MULTIFUNCTIONAL FILTER MATERIALS
(FR) MATÉRIAUX FILTRANTS MULTIFONCTIONNELS
Abstract
(EN) Embodiments include a filter material including an electrospun nanofiber membrane and an active nanomaterial agent incorporated into the electrospun nanofiber membrane, wherein the electrospun nanofiber membrane filters disease-causing agents and the wherein the active nanomaterial agent degrades disease-causing agents. Embodiments further include a face mask and/or respirator including a filter material, wherein the filter material includes an electrospun nanofiber membrane and an active nanomaterial agent incorporated into the electrospun nanofiber membrane, wherein the electrospun nanofiber membrane filters disease-causing agents and the wherein the active nanomaterial agent degrades disease-causing agents.
