  The work here has demonstrated the use a simple microwave plasma process for
welding carbon nanotubes onto solid surfaces such as plastics and glasses, it
was found that due to the lower softening point and viscosity of polystyrene
(compared to glass samples), welding of carbon nanotubes on polystyrene surface
can be achieved with higher efficiency, whilst the high softening point (and
melt viscosity) of lime-soda and borosilicate glasses prevents the nanotubes
from forming a continuous layer. Analysis of the quality of nanotubes by Raman
spectroscopy confirmed that some defects are introduced to the CNT graphitic
structure. However, these defects are not significant and can actually be
useful for some application.
