▎ 摘  要

NOVELTY - Filter element comprises a textile substrate comprising woven fabric and nonwoven fabric, and a composition comprising graphene, where the graphene consists of nano-platelets in which at least 90% have a lateral dimension (x, y) is 500-50000 nm and a thickness (z) of 0.34-50 nm, the content of graphene is 2-20 g graphene per square meter of textile substrate and is applied on all the textile substrate and inside it. The composition comprising graphene is free from antibacterial or antiviral agents comprising metal elements or metal compounds. USE - The filter element is useful for manufacturing air conditioning units for a motor vehicle (all claimed), and in civil and industrial sectors and for trapping dusts, fumes and atmospheric aerosol. ADVANTAGE - The filter element eliminates or reduces the passage and transmission of pathogenic agents such as bacteria, fungi and viruses. It minimizes the pressure drop of the air flow that passes through the filter. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for manufacturing a filter element. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the filter element.
