Abstract

Raman spectroscopy studies of oxygen-treated and sulfuric-acid-doped double-walled carbon nanotubes (DWNT) containing linear carbon chain were curried out. The results showed that the regularly developed triangle-like interstitial spaces in the bundled DWNTs with a specific area might act as a nanosized chemical container for the formation of linear carbons along the tube length or stabilize interstitial carbons. This would initiate the interconnection of the adjacent nanotube surfaces, forming short carbon chains circumferentially. Results suggested that there are other possibility for interstitially situated linear carbon chains in thermally treated, bundled DWNT papers. The interstitial spaces within large bundles of DWNTs were likely to be the most probable sites for the linear carbon chains, because thermally activated interstitial carbons were energetically lodged within the space.
