Graphene Solution is an aqueous and black liquid that is prepared by sonication of natural graphite in the mixture of ethanol/water. Its hydrophobic nature makes it challenging to be prepared in concentrated graphene solutions. Graphene is dispersed by using different surfactants. Homogeneously synthesized graphene is significantly used in various applications. Graphene solution is easily dissolved in water and other organic solvents. It is used in polymer composites, bio/chemical sensors, and catalysts.
