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.

X-ray photoelectron study of the surface of expanded and expandable graphite

Theoretical and Experimental Chemistry, 1993
Based on analysis of the x-ray photoelectron spectra of expandable graphite obtained in hydrolysis of graphite bisulfate and expanded graphite obtained upon thermolysis of intercalated graphite compound with trifluoroacetic acid, we determine the composition of the surface layer of these materials and we suggest a structure for the functional groups ...

Preparation of expandable graphite with ultrasound irradiation

Materials Letters, 2007
Abstract This article reports a new way to prepare expandable graphite with ultrasound irradiation. Flake graphite mixture and ultrasonic solvent were placed into a flask in the ultrasonic cleaning bath (nominal power of 500 W and 250 W) at room temperature. Ultrasonic time kept 60 min.

Preparation of Modified Expanded Graphite by KOH

Advanced Materials Research, 2011
A new material on adsorption of Pb(Ⅱ) was introduced in this paper. EG was modified by soaking in KOH. MEG (modified expanded graphite) was characterized by SEM, XRD and FTIR. The removal rate of Pb(Ⅱ) rose to 92.23% from 59.14% on MEG . And the adsorption quantity came up to 46.3869mg/g from 31.9662mg/g.

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 ...

Sorption of Industrial Oil by Expanded Graphite

Russian Journal of Applied Chemistry, 2003
Sorption of industrial oil by expanded graphite prepared from residual graphite hydrosylfate at 300-900°C was studied. The sorption isotherms of both neat oil and oil from its aqueous suspension were measured. The sorption capacity for oil was studied as influenced by the specific surface area and specific volume of expanded graphite sorbent.

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.
