Researchers find an easy way to make graphene - using heat and fluorine

Korean researchers found a new, easy way to make Graphene:  treating graphite with heat and a solution containing fluorine to produce expanded graphite -- graphite with widened gap between the layers -- which can then be placed in water-based solutions or organic solvents to produce graphene.

According to the research team, the new method is simpler and faster than existing methods of graphene production.
