▎ 摘　　要

NOVELTY - The material has a silver absorption nanometer granule layer formed on a graphene surface, where diameter of the silver absorption nanometer granule layer is 1-100 nm. A composite film material layer is formed with a gap. USE - Nano-particle interspersed graphene composite film material. ADVANTAGE - The material improves graphene photocurrent density and adjusts deposition time to change appearance of a nano-granule film, and has high light absorption efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing nano-particle interspersed graphene composite film material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a nano-particle interspersed graphene composite film material.
