Performance of expanded graphite and expanded milled‐graphite fillers in thermosetting resins
Polymer Composites, 2005AbstractEpoxy/expanded graphite (EG) and polyester/EG composites were prepared with the aid of sonication, while epoxy/expanded‐milled graphite (epoxy/milled‐EG) and polyester/expanded‐milled graphite (polyester/milled‐EG) composites were prepared on a three‐roll paint mill.

Absorption Process of Expanded Graphite
2010 4th International Conference on Bioinformatics and Biomedical Engineering, 2010Different expansion volume of expanded graphite was used for oil absorption experiments. The structure of expanded graphite was studied by scanning electron microscope (SEM) and optical microscope before oil-absorption and after oil-absorption. It was found that viscosity, expansion volume and particle size are the three key factors for the higher ...

On lower-nitrogen expandable graphite
Materials Research Bulletin, 2000Abstract The intercalation reaction of a mixture of HNO 3 and acetic anhydride to form expandable graphite was investigated. Expandable graphites were prepared from the intercalation compounds (GICs) by rapid heating up to 900°C. The effects of reaction conditions on the quality of the expandable graphites were studied and the optimum conditions for

Expanded graphite offers new opportunities
Plastics, Additives and Compounding, 2008Graphite 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, 2006AbstractA 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, 2014Expanded 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, 2012Using 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.
