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.
