Abstract:
Temperature dependences of the conductivity of onion-like carbon (OLC) and catalytic multiwalled carbon nanotubes
(MWNTs) were measured in various gas environments: helium, hydrogen, oxygen, air, methane. We have found that in the vicinity of the melting and vaporization temperatures of oxygen and methane the conductivity sharply decreases for MWNTs (by 2−12%) and for OLC (by 4-12%). The observed reversible changes of the conductivity of investigated samples are discussed in the terms of processes of gases adsorption-desorption on the surface of nanotubes and OLC and breakup-recovery of contacts between nanotubes and particles of OLC as a result of melting and vaporization of environment gases.
