Thermal characterization of expanded graphite and its composites

Inorganic Materials, 2007
Using the guarded hot plate method, we have measured the thermal conductivity of compressed expanded graphite (EG) samples (densities from 0.4 to 1.95 g/cm3) along the compression direction (c axis) in the range 150–675 K and that of EG/epoxy composites (5–75 wt % EG) in the range 150–425 K.

Sorption Properties of Thermally Expanded Graphite

Chemistry and Technology of Fuels and Oils, 2001
The powder was then heat treated at 1150 ‐ 1200 °C by blowing compressed nitrogen through a tubular electric furnace (quartz tube length of 80 cm, diameter of 2 cm) at a rate that ensured residence in the heat-treatment zone for 1.2 ‐ 1.3 sec. Important fluctuations in the temperature in the furnace were prevented by the small amounts of oxidized ...

Thermal degradation of polyurethane and polyurethane/expandable graphite coatings

Polymer Degradation and Stability, 2001
Abstract This study deals with the thermal degradation of polyurethane (PU) and polyurethane/expandable graphite (PU/EG) coatings. EG represents a new generation of intumescent additives which provides good fire retardancy to various materials and in particular to PU.

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 ...

Formation and properties of materials based on thermally expanded graphite

Powder Metallurgy and Metal Ceramics, 1997
It is established that the properties of articles made from thermally expanded graphite (TEG) depend mainly on methods and conditions of their formation. Material formation occurs in several stages. The capacity of TEG to show a considerable elastic aftereffect after removing the external load plays a special part in forming anisotropic properties ...

Expanded graphite/polydimethylsiloxane composites with high thermal conductivity

Journal of Applied Polymer Science, 2017
ABSTRACTExpanded graphite (EG)/polydimethylsiloxane (PDMS) composites with high thermal conductivity and high flexibility are prepared in this work. EG derived from natural graphite flake is infiltrated in PDMS prepolymer solution and then hot pressed in a steel mould at 80 °C for 2 h.

Morphological structure and microhardness of ground thermally expanded graphite

2017 IEEE 7th International Conference Nanomaterials: Application & Properties (NAP), 2017
The effect of the mechanical grinding on the structure and mechanical properties such as microhardness of the disperse thermally expanded graphite (TEG) has been studied. A comparison of the parameters of a deep structure of obtained TEG samples by X-ray diffraction method has been provided.

The Effect of Particle Size of Expandable Graphite on the Properties of an Expandable Thermal Insulation Material

Key Engineering Materials, 2016
An expandable thermal insulation material was prepared which can expand the volume at high temperature. The paper is aimed to study the effect of the particle size of expandable graphite for this material, through comparing properties including expansion rate, compression strength and heat conductivity coefficient.
