Preparation of graphene by exfoliation and its
Ball milling involves placing graphite, a grinding aid, and steel balls into a ball milling tank. During the rotation of the tank, the kinetic energy gained by the steel balls is transferred to the graphite as they collide with the graphite and other steel balls, thus exfoliating the graphene. High shear exfoliation involves placing the ...
