The channeling phenomenon of carbon ions in single-wall carbon nanotubes (SWCNTs) is investigated by using the molecular dynamics simulation with analytical potentials. The relationship between the channeling critical angles in the SWCNT and the bonding interaction is analyzed. It was found that, at 200–5000 eV and 10°–20° of incident angle, the ions with the bonding interaction or chemical effect, have decreased dechanneling probabilities and increased critical angles, compared to that of non-bonding ions. So the bonding effect cannot be ignored in the channeling mechanism of carbon ions through a SWCNT.
