METHOD FOR PREPARING SOLUBLE GRAPHENE SOLUTION AND COMPOSITE OF CARBON FIBER OXIDE AND POLYMER FROM CARBON FIBER

摘要

PURPOSE: A method for preparing a soluble graphene solution from carbon fibers and a method for preparing the composite of carbon fiber oxide and a polymer are provided to greatly reduce the cost because the starting material is pitch which is waste used for asphalt pavement; and to dispense with developing a mine for obtaining graphite because graphite is not used. CONSTITUTION: A method for preparing a soluble graphene solution comprises the steps of: forming carbon fiber oxide by oxidizing carbon fiber; forming a mixed solution of the carbon fiber oxide, a polymer non-covalently interacting with the carbon fiber oxide and a polar solvent; and reducing the carbon fiber oxide into graphenes by adding a reducing agent into the mixed solution.
