Title:
APPLICATION OF CARBON AND COPPER COMPOSITE NANOPARTICLES IN MELT-BLOWN NONWOVEN MATERIAL
Document Type and Number:
WIPO Patent Application WO/2022/077753
Kind Code:
A1
Abstract:
An application of carbon and copper composite nanoparticles as an antiviral additive and/or an electret material in a melt-blown nonwoven material. Carbon and copper composite nanoparticles comprise a Coppware R copper carbon R composite material; the Coppware R copper carbon R composite material comprises a carbon shell having a porous structure and copper nanoparticles wrapped in the carbon shell. Disclosed is an antiviral effect of the carbon and copper composite nanoparticles; in addition, when used in a melt-blown nonwoven material, the carbon and copper composite nanoparticles can function as an electret.
