Graphene oxide (GO) is an electrical insulator as most of the carbon atoms in this material are sp~3-hybridized. Its physical, optical and chemical properties depend on the type and degree of reduction process. Presently, copper ion irradiation of GO foil has been performed at Ion Beam ...
Chemical exfoliation is proposed to produce graphene oxide, using sulfur-free expanded graphite. X-ray diffraction was employed to evaluate the structural properties of expanded graphite, expanded graphite oxide, and graphene oxide. The FITR spectroscopy was used to demonstrate infrared spectroscopy charact...
The discovery of carbon nanotubes brought about bucky paper, which displays excellent mechanical and electrical properties that make it potentially suitable for fuel cell and structural composite applications.
