Carbon nanotubes (CNTs) can be used as nanoreactors due to their unique
hollow nanostructures. In order to prepare linear carbon chains inside
CNTs, eDIPS single-wall carbon nanotubes were annealed at high
temperatures from 1300 to 1500 in vacuum conditions. A Raman mode including three components between 1820 and 1880 cm−1
were observed in eDIPS carbon nanotube sample encapsulating linear
carbon chains. In addition, the intensity of the peaks corresponding to
the radial breathing mode of small diameter tubes became visible and
increased significantly after annealing, because thin inner tubes are
also formed inside the original tubes during the annealing process,
which are served as templates. This hints that the linear carbon chains
are actually synthesized inside the new inner CNTs with reduced
diameter. This study has important implications to understand the growth
and identification of linear carbon chains inside the CNTs.
