| titleOfInvention | The preparation method of graphene |
| abstract | The preparation method of graphene is the following steps are included: a) using graphite material as anode material, sour and hydrogen peroxide mixed solution carries out cell reaction realization to the electrochemical stripping of anode material as electrolyte；B) electrolyte after reacting in step a is separated by solid-liquid separation and is washed, to extract the graphene presoma of dispersion in the electrolytic solution, then the graphene presoma extracted is subjected to drying and processing and obtains graphene sample；C) graphene sample dried in step b is dissolved in organic solvent, then the organic solvent dissolved with graphene sample is ultrasonically treated, obtain graphene solution.Graphene of the invention provides a kind of preparation method, is that electrolyte realizes the electrochemical stripping to graphite material under electric field action by using the mixed solution of hydrogen peroxide and acid, realizes that removal of impurities is simple thoroughly, inexpensive and pollution-free prepare graphene；By the electrolyte based on hydrogen peroxide, supplemented by acid, clean and environmental protection improves the purity and quality of product. |
