NOVELTY - Graphene solution preparation involves preparing natural graphite powder into oxidized graphite solid through oxidizing by interlayer. The oxidized graphite solid is prepared into single layer graphene oxide solution. Ammonia water and hydroxylamine hydrochloride are reacted for obtaining graphene solution. USE - Method for preparing graphene solution (claimed). ADVANTAGE - The method enables to prepare uniform and dispersed graphene solution.
