Fabrication of Reduced Graphene Oxide By Using Supercritical Fluid Techonology

Graphene has attracted great deal of interest in recent years on account of its excellent mechanical, physical, chemical and electronic properties, and its great potential in applications.

Supercritical fluid technology based on beneficial physical properties of supercritical fluids, including extremely low viscosity, high diffusivity, zero surface tension, and environmental benignity can provide one of the best economically viable route for large-scale production of graphene and its derivatives.

The team at chemistry faculty of Kim Il Sung University has developed the novel approach for preparation of reduced graphene oxide of high-quality using supercritical fluid technology. They believe that their new approach can provide high-quality bulk reduced graphene oxide at lower price facilitating application in a variety of fields including energy storage, sericultural industy, in medicine etc.

Technical specifications of the reduced graphene oxide are as follows:

C/O=12.7, I_D/I_G/=0.6, S _BET / =350 m²/g, ρ=0.06 g/cm³, number of layers 2~3.
