▎ 摘　　要

NOVELTY - Liquid phase automatic dispersion graphene solid comprises (A) graphene, and (b) a dispersing substance which is used to disperse the graphene in a liquid phase, where the dispersed substance comprises a first substance, a second substance, and an optional surfactant, and the first substance and the second substance reacts to form a gas in the liquid phase. USE - The graphene solid is used for preparing a substance such as coating material, a composite material, a conductive and thermally conductive paste, and an adhesive, and used in an article (all claimed). ADVANTAGE - The graphene solid is easy to transport, and is easily, quickly and efficiently dispersed during use. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method of preparing the graphene solid comprising (a) providing and mixing graphene, a first substance, a second substance and an optionally surfactant and (b) tabletting to obtain the product; and (2) a method for automatically dispersing graphene liquid phase comprising the step (a), (b) and (c) placing the graphene solid obtained in step (a) in a liquid phase, so that the liquid phase of graphene is automatically dispersed.
