摘要： The present invention provides a method of producing pristine or non-oxidized nano graphene platelets (NGPs) that are highly conductive. The method comprises: (a) providing a pristine graphitic material comprising at least a graphite crystallite having at least a graphene plane and an edge surface; (b) dispersing multiple particles of the pristine graphitic material in a liquid medium containing therein no surfactant to produce a suspension, wherein the multiple particles in the liquid have a concentration greater than 0.1 mg/mL and the liquid medium is characterized by having a surface tension that enables wetting of the liquid on a graphene plane exhibiting a contact angle less than 90 degrees; and (c) exposing the suspension to direct ultrasonication at a sufficient energy or intensity level for a sufficient length of time to produce the NGPs. Pristine NGPs can be used as a conductive additive in transparent electrodes for solar cells or flat panel displays (e.g., to replace expensive indium-tin oxide), battery and supercapacitor electrodes, and nanocomposites for electromagnetic wave interference (EMI) shielding, static charge dissipation, and fuel cell bipolar plate applications.
