Abstract:
Temperature dependences of the conductivity of catalytic multiwalled carbon nanotubes (MWNTs) were measured in various environments: helium, hydrogen, oxygen, air and methane. We had found that in the vicinity of the melting and vaporization temperatures of hydrogen, oxygen, air and methane the conductivity sharply decreases by (2–12%). The observed reversible change of the conductivity is connected with the adsorption–desorption of gases on the surface of nanotubes and breakup-recovery of contacts between nanotubes as a result of melting and vaporization of hydrogen, oxygen, air and methane.
