Experimental investigation of concentration yields of liquid phase exfoliated graphene in organic solvent media

The main purpose of this work is to experimentally investigate the concentration yields of exfoliated Graphene in organic solvents with the variation of different centrifugation speeds (rpm). Graphene was effectively fabricated by one of the most convenient chemical processing approach liquid-pha...
