Enhanced field emission from polyaniline coated amorphous carbon nanotubes

Abstract

Amorphous carbon nanotubes-polyaniline composite have been synthesized by simple chemical procedure. It has been found from the field emission scanning electron microscopy and transmission electron microscopy that amorphous carbon nanotubes are coated with the polyaniline. As synthesized polyaniline coated amorphous carbon nanotubes showed improve field emission property with a turn-on field as low 2.77 V/ μm.
