Researchers from Korea's Ulsan National Institute of Science and Technology (UNIST) developed a simple and efficient way to produce Edge-selectively functionalized graphene nanoplatelets (EFGnPs) from graphite. The researchers are actually grinding graphite using a dry ball mill. The presence of chemical vapors, liquids or solids in the ball-mill crushes results in the creation of various functional groups.
Using various microscopic and spectroscopic measurements, the reaction mechanisms for the edge functionalization of graphite was confirmed.
