General description
Structure of double walled carbon nanotubes (DWNTs) can be imagined as a two coaxial concentric single walled carbon nanotubes (SWNTs). It has been prepared by catalytic chemical vapor deposition. DWNTs exhibit excellent field emission properties and may be potentially useful as field emission displays (FEDs) and field emission transistors (FETs).
Application
Carbon nanotube, double walled can be used for a variety of applications such as solar cells, nanomechanical resonators, film heaters, biosensors, and field emission displays.
Packaging
Packaged in glass bottles
Preparation Note
Chemical Vapor Deposition (CVD) Method
Analysis Note
50-80% DWNT content, 10-40% other CNTs, remainder being amorphous carbon and residual metal catalysts.
