▎ 摘　　要

NOVELTY - Manufacture of graphene-silver composite involves uniformly mixing graphene oxide suspension and silver ion solution, obtaining composite mixture, filtering, and forming composite film using L-ascorbic acid aqueous solution as vapor-reducing agent. USE - Manufacture of graphene-silver composite used in preparation of fungicide and surface-enhanced Raman-effect application (all claimed). ADVANTAGE - The method enables simple and environmentally-friendly manufacture of graphene-silver composite having three-dimensional network structure, without using chemical reagent.
