Carbon Nanotubes Properties and Applications

Furthermore, the high-frequency carbon-carbon bond vibrations provide an intrinsic thermal conductivity higher than even diamond. In most materials, however, the actual observed material properties – strength, electrical conductivity, etc. – are degraded very substantially by the occurrence of defects in their structure.

Synthesis of graphene: Potential carbon precursors and

Graphene has a high electrical conductivity due to the free movement of electrons in the π-electron clouds and a high thermal conductivity due to the strong bonding of its carbon atoms [38,39]. Furthermore, a molecular dynamics simulation [ 40 ] revealed monolayer graphene displays auxeticity, particularly at increasing temperatures, which enhances graphene's macroscopic properties such as

2012/8/27High-density buckypapers were obtained by using well-aligned carbon nanotube arrays. The density of the buckypapers was as high as 1.39 g cm–3, which is close to the ultimate density of ideal buckypapers. Then we measured the transport and mechanical properties of the buckypapers. Our results demonstrated that its electrical and thermal conductivities could be almost linearly improved by
