▎ 摘　　要

NOVELTY - Preparation of graphene comprises mixing alkali solution in which graphite powder is dispersed with soluble salt to obtain a mixed solution containing grinding aid, where grinding aid portion is analyzed and dispersed in the mixed solution, precipitating, stirring to obtain graphene dispersion, washing, and drying. USE - The method is used for preparing graphene for stripping two-dimension nanomaterial (claimed). ADVANTAGE - The method is a one-step method, does not require additional intercalation, does not need to be stripped under acidic conditions, avoids acid pollution to the environment and equipment, and is environmentally friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for stripping method of two-dimension nanomaterial comprising dispersing two-dimensional material with mixed solution of alkali soluble salts solution, reacting, dispersing in the mixed solution with grinding aid, precipitating, and stirring, where two-dimensional material is graphite, boron nitride, molybdenum disulfide, tungsten diselenide, tungsten(IV) telluride, molybdenum trioxide, and/or trinickel germanide ditelluride.
