Double walled CNT is an emerging class that consists of two
concentric carbon nanotubes. They also possess increased mechanical strength
and thermal stability with increased electronic and optical properties. It also
has the capability to become novel sensors and to be used in electronic devices.
Which exhibit various other properties, including improvement in a lifetime and
current density for field emissions. They are highly stable against aggressive
chemical, thermal and mechanical treatments. Their applications include its use
in conductive plastic parts, parts of aircraft, anti-static fuel hoses and
electronics, etc.
