Native Graphene Oxides at Graphene Edges

IEEE Transactions on Instrumentation and Measurement, 2012
The boundary between graphene flake and SiO 2 /Si substrate have been probed by scanning capacitance microscopy. Distinctive dot-like protrusions standing on the graphene edges have been observed, and the density of protrusions increases with the increase of graphene layer numbers. Spectroscopic analysis has revealed that the carrier densities at these

Dispersion behaviour of graphene oxide and reduced graphene oxide

Journal of Colloid and Interface Science, 2014
The dispersion behaviour of graphene oxide (GO) and chemically reduced GO (rGO) has been investigated in a wide range of organic solvents. The effect of the reduction process on the GO solubility in eighteen different solvents was examined and analysed, taking into consideration the solvent polarity, the surface tension and the Hansen and Hildebrand ...

Electrorheology of Graphene Oxide

ACS Applied Materials & Interfaces, 2012
Novel polarizable graphene oxide (GO) particles with oxidized groups on their edge and basal planes were prepared by a modified Hummers method, and their electro-responsive electrorheological (ER) characteristics when dispersed in silicone oil were examined with and without an electric field applied. The fibrillation phenomenon of this GO-based electro-

Graphene Oxide Nanocolloids

Journal of the American Chemical Society, 2010
Graphene oxide (GO) nanocolloids-sheets with lateral dimension smaller than 100 nm-were synthesized by chemical exfoliation of graphite nanofibers, in which the graphene planes are coin-stacked along the length of the nanofibers. Since the upper size limit is predetermined by the diameter of the nanofiber precursor, the size distribution of the GO ...

Magnetic Characteristics of Graphene Oxide and Reduced Graphene Oxide

Materials Science Forum, 2021
Graphene oxide (GO) is 2D material made of honey comb carbon structure as backbone and decorated by oxygen functional groups in both sides. These functional groups have role to the GO properties, such as magnetic susceptibility, band gap, conductivity.

From Graphite to Graphene Oxide and Graphene Oxide Quantum Dots

Small, 2017
Many methods have been reported for synthesizing graphene oxide (GO) and graphene oxide quantum dots (GOQDs) where a tedious operational procedure and long reaction time are generally required. Herein, a facile one‐pot solvothermal method that allows selective synthesis of pure GO and pure GOQDs, respectively is demonstrated.
