Abstract

Graphene is a new advanced material for microelectronics. Graphene films can be prepared by different techniques. One of the promising methods is the production of stable dispersions of graphene in water or organic solvents. We have developed a new approach for preparation of easily soluble expanded graphite using fluorinated graphite intercalation compounds as starting materials. Graphene sheets obtained from water dispersions showed high conductivity and transparency. This technique can be used for the low-cost mass production of graphene for various applications because of the simplicity and speed of the process. Moreover, when doped with nitrogen, our new form of expanded graphite is a perspective material for field emission cathodes.
