Abstract
The invention provides a method for separating submicron fraction of carbon nano-materials. The method includes grinding of the carbon nano-materials. Upon grinding, the carbon nano-materials are mixed in water to prepare a mixture. The mixture is then treated in an ultrasonic bath to prepare a suspension. The suspension is allowed to undergo a liquid sedimentation. After the liquid sedimentation, a supernatant is collected and filtered to obtain a solid residue of the submicron fraction of the carbon nano-materials.
