▎ 摘　　要

NOVELTY - Intelligent graphene heat conductive film comprises a base layer (1) and an additional layer (2), where the base layer is a film layer of a two-dimensional graphene nanosheet and a one-dimensional graphene nanoribbon. The base layer comprises 5-10 pts. wt. polyvinylpyrrolidone, 3-8 pts. wt. silica nano powder, 3-8 pts. wt. titanium dioxide nano powder, 20-30 pts. wt. graphene material, 25-50 pts. wt. isopropanol, 2-8 pts. wt. sodium carboxymethylcellulose and 1 pt. wt. of initiator. The additional layer is attached to both sides of the aforementioned base layer, where the additional two-dimensional graphene nanosheet layer is impregnated by the multilayer. USE - Intelligent graphene heat conductive film. ADVANTAGE - The intelligent graphene heat conductive film has overall satisfied thermal conductivity, and improves flexibility. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing intelligent graphene heat conductive film, which involves: (A) uniformly dispersing raw materials in double distilled water and absolute ethanol to obtain a suspension; (B) subjecting the obtained suspension to ultrasonic treatment to prepare a uniform and dense filter on the filter funnel; (C) using suspension of excess sonicated filter to form graphene film on the surface of the filter; (D) using 0.1- 0.3M hydrochloric acid or sodium hydroxide aqueous solution as a removal solution for immersing filter membrane and the graphene film for 3-12 minutes; (E) placing the combined body under low temperature decompression of ethanol, isopropanol or acetone; (F) removing the filter in steam for 1-5 hours; (G) drying under vacuum at normal temperature for 24-72 hours to obtain uniform and stable graphene film as base layer; (H) forming film layer by spin coating by using a sufficient amount of graphene suspension to form graphene spin-on additional layer on one side of the base layer; and (I) forming film layer by spin coating by using a sufficient amount of the graphene suspension. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic vertical cross-sectional structure of the intelligent graphene heat conductive film. Base layer (1) Additional layers (2,3)
