  The poor thermal conductivity of bulk polymers may be enhanced by combining
them with high thermal conductivity materials such as carbon nanotubes.
Different from random doping, we find that the aligned carbon
nanotube-polyethylene composites (ACPCs) has a high thermal conductivity by
non-equilibrium molecular dynamics simulations. The analyses indicate that the
aligned structure can not only take advantage of the high thermal conduction of
carbon nanotubes, but enhance thermal conduction of polyethylene (PE) chains.
Our predictions may inspire manufacturing aligned polymer-based composites for
a wide variety of applications.
