The Effective Density and Transport Properties of Compacted Carbon Nanotubes and Nanowhiskers.

We have studied the effective density, electric conductivity, and thermo emf of compacted carbon nanotubes (NTs) and nanowhiskers (NWs). The effective densities of NTs and NWs are 1.6 and 2.8g/cm3 respectively. The thermo emf of compacted NWs (33μV/K) and NTs (7–8μV/K) make it possible to use these materials in sensors of molecular gases and biological objects. It is also recommended to introduce NWs and NTs as fillers into glue compositions possessing increased strength and electric conductivity, which are necessary for gluing metals. © 2005 Pleiades Publishing, Inc.
