Expanded graphite offers new opportunities

Plastics, Additives and Compounding, 2008
Graphite has been overlooked in the past as additive for polymers. C. Ciallella, T.M. Gruenberger, E. Grivei and N. Probst of Timcal explain why a reconsideration is required.

Fabrication of polyethylene/graphite nanocomposite from modified expanded graphite

Polymer International, 2006
AbstractA novel process was employed to fabricate a polymer/expanded graphite nanocomposite by modifying the conducting filler expanded graphite (EG) with unsaturated polyester resin (UPR). The modified expanded graphite (MEG) was prepared from EG in which the graphite nanosheets, already present in EG, were wrapped and isolated by the UPR during ...

Nanoporous Graphite Materials Produced by Ball-Milling Expanded Graphite

Applied Mechanics and Materials, 2014
Expanded graphite was ball-milled for 80 h in a high-energy mill (planetary-type) under an air atmosphere. The products were characterized by scanning electron microscopy. The results show that ball-milling EG produces nanoporous graphite powders.

Size Effect of Expandable Graphite

Advanced Materials Research, 2012
Using three natural graphites with different particle size, 35, 50 and 80 mesh, as raw materials, expandable graphites were prepared by intercalating, water-washing and drying the natural graphites. The products were characterized by X-ray diffraction, Infrared spectroscopy, scanning electron microscope and Raman spectroscopy.

Preparation and Characteristics of Expanded Graphite

Advanced Materials Research, 2011
Expanded graphite (EG) was prepared using fine flake graphite that could go through 50 mesh as raw material, perchloric acid as inserting agent and concentrated nitric acid as oxidant. The effects of amount of raw materials, reaction time and reaction temperature on expanded volume and sorption capacity of EG were studied, and microstructure of EG were

Colloidal-Graphite Suspension Based on Thermally Expanded Graphite

Russian Journal of Physical Chemistry B
Currently, modified oxidized (intercalated) graphites and thermally expanded graphites obtained from them are used in solving many applied problems. This is due to the fact that while retaining all the properties of layered graphite compounds, split graphite particles have important new properties, such as ease of molding, low bulk density, and active ...

Surface area of compressed expanded graphite

Carbon, 2002
In a previous work [Carbon (2002) in press], the densification of expanded graphite was modelled. This very light material consists of worm- or accordion-like particles in a loose packing. Worm-like particles are made up of thin disc-shaped graphite sheets, and the average disorientation angle of the thin discs was estimated based on the excluded ...

Intercalation of CuCl2 into expanded graphite

Carbon, 1997
In this study, we have successfully synthesized CuCl 2 -GIC flakes with a particle size 0,5-2 mm by using expanded graphite. A chloride of lower Cl 2 pressure might also intercalate into graphite.

Effect of Expansion Temperature of Expandable Graphite on Anti-Friction Effect of Graphite Nonasheets from Sonicating Expanded Graphite

Applied Mechanics and Materials, 2011
Three graphite nanosheets were prepared by sonicating three expanded graphites that were formed by rapidly heating expandable graphite at 600, 800 and 1000 °C, respectively. The graphite nanosheets were characterized by scanning electron microscope. The anti-friction effects of the graphite nanosheets used as lubricating additives were investigated ...
