Abstract EN
The graphene double-walled carbon nanotube (DWCNT) hybrid films were prepared by vacuum filtration and screen printing.
Their electron field emission properties have been studied systematically.
The electron emission properties of the hybrid films are much better than those of pure DWCNT films and pure graphene films.
Comparing with the screen printed films, the vacuum filtered films have many advantages, such as lower turn-on field, higher emission current density, better uniformity, better long-term stability, and stronger adhesive strength with conductive substrates.
The optimized hybrid films with 20% weight ratio of graphene, which were fabricated by vacuum filtration, show the best electron emission performances with a low turn-on field of 0.50 Vμm−1 (at 1 μAcm−2) and a high field enhancement factor β of 27000.
