Graphite solvent
WebOct 28, 2010 · a) Direct sonication of graphite in ethanol results in complete precipitation after 4 h (left) while a stable graphene dispersion in ethanol is obtained using the solvent exchange process (right). WebGraphite is insoluble in water as well as other organic solvents. There are no attractive forces that occur between the solvent molecules and the carbons atoms in its structure, and thus, it fails to dissolve in any of the organic solvents. Electrical Conductivity There is a vast delocalization of electrons within the carbon layers of graphite.
