Abstract: The present disclosure relates to a method for manufacturing graphene based on a mixed inorganic acid solvent. By using the inorganic acid solvent with simple preparation and low-cost instead of expensive organic solvent to perform a solvent stripping method for manufacturing graphene products, it may avoid the problems of high toxicity and harsh preparation conditions caused by using organic solvents, reduce the requirement on temperature in the graphene preparation process of the solvent stripping method, and reduce the time required by graphene stripping treatment; thereby simplifying the preparation process, and facilitating the commercialization and large-scale development of the method for manufacturing graphene by the solvent stripping method.
