▎ 摘　　要

NOVELTY - Graphene spraying agent comprises a mixed solution of graphene solution and photocatalyst. USE - The graphene spraying agent is useful for coating waterproof and air permeable outdoor articles (claimed). ADVANTAGE - The graphene spraying agent can be prepared easily and economically; and is convenient to carry. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) the preparation of the graphene spraying agent comprising preparing graphene powder by redox process, adding a solvent to the prepared graphene powder and stirring to obtain graphene solution, adding the obtained graphene solution to photocatalyst and purifying the mixture by the centrifugation of the mixed solution, and taking the supernatant containing the graphene and photocatalyst; and (2) use of the graphene spraying agent for waterproof and air permeable outdoor articles, where the application takes place by directly spraying the graphene agent on the surface of the outdoor articles.
