Schematic of a thin CNT film deposition on a plate by electropholysis.
SEM images of the gelatinized thin films prepared by electrophoretic deposition of CNTs on a Ti substrate and then dried naturally: before (a) and after (b) being pressed by covering with a glass slide on the gelatinized thin film of CNTs. The CNTs were SWNTs made by arc discharge.
SEM images of the CNT films deposited on Ti substrates after the fissure formation process; a low (a) and high (b), (c) magnification images of the CNT thin films. Clean CNTs exist between microislands like tightened strings (b) and some of the CNTs are cut between islands (c).
Typical field-emission current density vs the applied electric field for the CNT thin film prepared by our method. Inset is the field emission image of the CNT thin film by applying a field of .
