Microhardness of сompacted thermally expanded graphite

Bulletin of Taras Shevchenko National University of Kyiv. Series: Physics and Mathematics, 2019
Using the method of continuous microindentation with different loading on the indenter, the microhardness of compacted thermo-expanded graphite (TEG) samples of different dispersion was studied. The analysis of the obtained results showed that, with an increase in the average cross-sectional area of TEG particles from 40 to 120 microns, the ...

Hydrogen-Peroxide Intercalated Expanded Graphite Facilitates Large Enhancement in Thermal Conductivity of Polyethermide/Graphite Nanocomposites

Journal of Materials Research and Technology, 2023
In this work, we prepared expanded graphite (EG) filler using hydrogen peroxide (H2O2) as an oxidizing agent to study its impact on the thermal conductivity (k) of polyetherimide (PEI) composite, compared to EG prepared using sodium chlorate (NaClO3). Sulfuric acid was used as the primary intercalating agent for both synthesis routes.
