Simple Method for the Preparation of Composites Based on PA6 and Partially Exfoliated Graphite [PDF]

open access: yes, 2012
In the present work, the preparation of composite systems based on polyamide 6 (PA6) and exfoliated graphite was attempted by applying a simple procedure, which consists of a preliminary dispersion/exfoliation of graphite in the monomer, namely, ε ...

Transmission Electron Microscopy Study of Graphite underin situIon Irradiation [PDF]

open access: yes, 2012
Graphite is employed as a moderator and structural component in 18 of the UK's fleet of Magnox and Advanced Gas-cooled Reactors (AGRs). During the operational lifetime of a reactor, graphite undergoes complex physical and mechanical property changes ...

Avant-Garde Polymer and Nano-Graphite-Derived Nanocomposites—Versatility and Implications

open access: yesC, 2023
Graphite (stacked graphene layers) has been modified in several ways to enhance its potential properties/utilities. One approach is to convert graphite into a unique ‘nano-graphite’ form.

Superlubricity of Graphite

open access: yesPhysical Review Letters, 2004
Using a home-built frictional force microscope that is able to detect forces in three dimensions with a lateral force resolution down to 15 pN, we have studied the energy dissipation between a tungsten tip sliding over a graphite surface in dry contact.

Ultraviolet-visible spectroscopy of graphene oxides

open access: yesAIP Advances, 2012
Dispersions of few-layer (1-3 layers), multi-layer (4-10 layers) and thick-layer (>10 layers) graphene oxide (GO) were prepared by a modified Hummers method with different mass ratios of KMnO4 to graphite.

Evaluation and Characterization of Reduced Graphene Oxide Nanosheets as Anode Materials for Lithium-Ion Batteries

open access: yesInternational Journal of Electrochemical Science, 2013
High quality reduced graphene oxide (rGO) nanosheets were prepared from natural graphite through oxidation followed by solvothermal reduction method. The morphology, structure and composition of graphene oxide (GO) and rGO were characterized by scanning ...
