The effect of sorbed hydrogen on low temperature radial thermal expansion of single-walled carbon nanotube bundles
The effect of a normal H₂ impurity upon the radial thermal expansion ar of single-walled carbon nanotube (SWNT) bundles has been investigated in the interval T = 2.2–27 K using the dilatometric method. It is found that H₂ saturation of SWNT bundles causes a shift of the temperature interval of the n...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The effect of a normal H₂ impurity upon the radial thermal expansion ar of single-walled carbon nanotube (SWNT) bundles has been investigated in the interval T = 2.2–27 K using the dilatometric method. It is found that H₂ saturation of SWNT bundles causes a shift of the temperature interval of the negative thermal expansion towards lower (as compared to pure carbon nanotubes) temperatures and a sharp increase in the magnitude of ar in the whole range of temperatures investigated. The low temperature desorption of H₂ from a powder consisting of bundles of SWNTs, open and closed at the ends, has been investigated. |
