Abstract
Methods and devices are provided relating to the homogeneous deposition of a composite film of carbon nanotubes by electrophoresis. The methods comprise linking carbon nanotubes to matrix particles prior to electrophoretic deposition. The methods improve the adhesion of the composite film to the substrate and reduce the surface roughness. Carbon nanotube films and electron field emission cathodes fabricated by this process demonstrate enhanced electron field emission characteristics.
