▎ 摘　　要

NOVELTY - Graphene oxide-modified activated carbon preparation involves adding activated carbon to graphene oxide solution, stirring obtained mixture for 6-12 hours, filtering, and then collecting filter residue. The filter residue is dried to obtain graphene oxide-modified activated carbon. USE - Method for preparing graphene oxide-modified activated carbon for use in oxidized graphene modified active carbon mask (all claimed). ADVANTAGE - The method prepares the graphene oxide-modified activated carbon in a simple, cost-effective and eco-friendly manner with improved tamper resistance, excellent antibacterial properties, ultraviolet ray resistance and far infrared heat generation performance of the mask. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an oxidized graphene modified active carbon mask, which comprises non-woven surface layer (1), graphene modified activated carbon composite non-woven layer (2), activated carbon non-woven layer (3), and non-woven underlayer (4). DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the graphene oxide modified activated carbon mask.
