Comparison on different post-treatment methods of printed carbon nanotube films for enhanced field emission

Four kinds of different post-treatment methods or conditions, including low residue adhesive tape treatment, high residue adhesive tape treatment, plasma exposure treatment and mechanical crushing and blowing treatment, were applied to screen-printed carbon nanotube (CNT) films to improve their field emission ability. The effects and results of these methods or conditions on field emission characteristics of printed CNT films were compared in some aspects such as I-V curves, luminescent images and annealing treatment and so on.
