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 ...

Short-lasting fire in partially and completely cured epoxy coatings containing expandable graphite and halloysite nanotube additives

Progress in Organic Coatings, 2018
Epoxy coatings containing halloysite nanotubes (HNTs) and expandable graphite (EG) are prepared and cured by the aid of an amine hardener varying the curing time and filler content, and then thermal degradation and fire retardancy of samples are ...

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 ...

HDPE/expanded graphite electrically conducting composite

Composite Interfaces, 2004
In this study, HDPE/expanded graphite electrically conducting composites were prepared in the presence of expanded graphite (EG) via a melt-blending process. The microstructure, electrical, mechanical and thermal properties of the resulting HDPE/EG composites were investigated. The experimental results revealed that EG could be dispersed in the form of

Evaluation of the expandable graphite/polyaniline combination in intumescent coatings

Synthetic metals, 2019
In this study, the addition of expandable graphite to paints containing polyaniline (PANI) and ammonium polyphosphate (APP) as pigments was investigated in order to improve the fire protection performance of the intumescent coatings.

Effect of Expanded Graphite Lattice in Exfoliated Graphite Nanofibers on Hydrogen Storage

The Journal of Physical Chemistry B, 2005
A graphite exfoliation technique, using intercalation of a concentrated sulfuric/nitric acid mixture followed by a thermal shock, has successfully exfoliated a herringbone graphite nanofiber (GNF). The exfoliated GNF retains the overall nanosized dimensions of the original GNF, with the exfoliation temperature determining the degree of induced defects,

Preparation, quantitative surface analysis, intercalation characteristics and industrial implications of low temperature expandable graphite

Applications of Surface Science, 2018
Expandable graphite is widely used as a new functional carbon material, especially as fire-retardant; however, its practical application is limited due to the high expansion temperature.

Highly effective flame retarded polystyrene by synergistic effects between expandable graphite and aluminum hypophosphite

Polymer degradation and stability, 2018
Herein, expandable graphite (EG) and aluminum hypophosphite (AP) are used to prepare flame-retardant polystyrene (PS) composites. The flame-retardant properties of the PS composites are investigated by the limiting oxygen index (LOI) test, vertical ...
