Graphene's electrical conductivity as a result of the delocalised π electrons is many orders of magnitude larger than silicon (1.56×102 S/m) which is commonly used in electronic devices. It's thermal conductivity is also outstanding making it suitable for applications in thermal management, such...
8. Reduced graphene nano-sheets CV DPV 1–100 32 AA DA Highly reduced graphene had a smaller electric resistance and higher conductivity than those of GO – Kim et al. (2012) CA 9. G-g-PLA-Pd CV 0.1–100 80 DA UA AA H2O2 Electrical conductivity of G-g-PLA-Pd was largely enhanced...
Moreover, the excellent electrical and thermal conductivity of graphite has enabled it to be used as electrodes and heating elements in the blast furnace in industries (Delhaes, 2001; Enoki et al., 2003). The single sheet of graphite termed as graphene was first reported in 1987 as one of ...

Due to the difficulty of mass-producing graphene films, it remains an extremely expensive material. Graphite is a key material used in the fabrication of lithium-ion battery (LIB) anodes. The properties of graphite, such as high thermal and electrical conductivity, excellent mechanical properties, ...
where \({\sigma }_{e}\) is the electrical conductivity and \({J}_{e}\) represents the electron flux. The lithium concentration in graphite particles (cs) is solved according to a microscopic mass balance along the particle radius as: $$F\frac{\partial {c}_{s}}{\partial t}+\nabla...
Graphite is used in pencils, lubricants,crucibles, foundry facings, polishes, brushes for electric motors, and cores of nuclear reactors. Its highthermaland electrical conductivity make it a key part of steelmaking, where it is used as electrodes inelectric arcfurnaces. In the early 21st century...
The electrical conductivity of N-doped REGO depends on the synthesis and reduction methods. It has been reported that the electrical conductivity of N-doped graphene synthesized by the Hummer’s method and reduced under N2 is 56.8 Scm−1 [22], but when reduced under NH3 at 800 °C it ...
Polyaniline (PANI)/graphene oxide (GO) composites were synthesized via in situ polymerization of aniline in the presence of GO. The effect of microwave treatment of graphite on the electrical conductivity and electrochemical properties of PANI/GO composi
