✦ Synopsis

Complete analytical solutions of the one-dimensional x-band structures of single-shell carbon nanotubes considering all the plausible bond-alternation patterns are afforded based on the tight-binding crystal orbital method in the framework of the Hilckel approximation. It has been found that there are still two classes of the nanotubes showing small and large band gaps even after the introduction of the bond alternations. The bond-alternation patterns which give the largest band-gap values depend on the conformation series of the tubes.

## Abstract A structural analysis of an increasing plasticity effect for polymer nanocomposites filled with carbon nanotubes was carried out. It was shown that this effect was due to densely packed interfacial layer formation on an atomic scale on the smooth nanotube surfaces, which resulted in cha
