▎ 摘　　要

NOVELTY - A flower-shaped graphene comprises several graphene aggregates which are formed by curling single-layer or multi-layer ultra-thin two-dimensional nanomaterial. The single-layer graphene aggregate has size of 50-200 nm. USE - Flower-shaped graphene used in manufacture of melt-blown cloth (claimed) for mask. ADVANTAGE - The flower-shaped graphene material can effectively improve the permeability of the filter performance of the composite melt-blown cloth, and endows excellent antibacterial performance and mechanical property. The melt blown cloth prepared by the flower-shaped graphene has oleophilic and hydrophobic, antibacterial, strong adsorption capacity and excellent performance, and the prepared mask has great practical application value in the anti-attack epidemic. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation of the flower-shaped graphene.
