SINTESIS GRAPHENE OXIDE DAN REDUCED GRAPHENE OXIDE

PROSIDING SEMINAR NASIONAL FISIKA (E-JOURNAL) SNF2016 UNJ, 2016
Graphene oxide (GO) and reduced graphene oxide (rGO) have been synthesized chemically from graphite powder. Graphite powder was oxidized with strong oxidator agent molekul  to get graphite oxide, this process was called by Hummer’s methode. Graphite oxide was dispersed in water with ultasonic vibrator to exfoliated graphite oxide layers, and ...

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 ...

Substrate-Sensitive Graphene Oxidation

The Journal of Physical Chemistry Letters, 2016
The inertness of graphene toward reaction with ambient molecules is essential for realizing durable devices with stable performance. Many device applications require graphene to contact with substrates, but whose impact on the chemical property of graphene has been largely overlooked.

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.

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-

Facile hydrothermal preparation of graphene oxide nanoribbons from graphene oxide

Chemical Communications, 2013
Graphene oxide nanoribbons (GONR) with regular edges have been prepared by a facile hydrothermal method. The relatively high yield and convenient preparation of GONR eventually make graphene nanoribbons (GNR) accessible in the field of composite materials where bulk quantities of nanoribbons are required.
