▎ 摘  要

NOVELTY - Graphene is produced by splitting graphite using electrostatic repulsion forces. The initial graphite crystal is charged to a potential of 200 thousand Volt, between 2-10 million volts. Potential of 10-100 million volts can also be used. The potential can be produced using a Van de Graff generator. The process can be carried out in following media: atmosphere, inert gas, insulating liquid, liquefied inert gas or vacuum. USE - For production of graphene from graphite used in electronics, instrument making and nanotechnology. ADVANTAGE - The production costs are reduced whilst increasing the graphene purity an environmental pollution is reduced. The process allows the use of natural, synthetic or pyrolitic graphite, graphite oxide, graphite fluoride or carbon fiber and carbon nano-fibers.
