Producing isolated graphene sheets from supply of coke or coal powder, used in composite material, comprises dispersing particles of coke or coal powder in liquid medium to produce suspension, and exposing suspension to ultrasonication.

ZHAMU A, JANG B Z

Producing chemically functionalized nano graphene material involves mixing starting nano graphene material, azide/bi-radical compound, and organic solvent in reactor and allowing chemical reaction between the material and the azide compound.
