▎ 摘　　要

NOVELTY - The MXene/rGO composite film has a first reduced graphene oxide film layer (1), a second reduced graphene oxide film layer (3) and a middle film layer (2). The middle film layer is arranged between the first reduced graphene oxide film layer and the second reduced graphene oxide film layer. The middle film layer includes an MXene film layer. The graphene oxide dispersion liquid is provided and the organic filter film is placed on the funnel. The first reducing graphene oxide film layer is obtained. USE - MXene/rGO composite film for generating sound used in flexible acoustic device (claimed). ADVANTAGE - The MXene/rGO composite film is featured with high frequency response uniformity, good flexibility, good conductivity, stable device performance, high thermoacoustic efficiency, and no substrate Joule heat generation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing MXene/rGO composite film. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of MXene/rGO composite film for generating sound.
