Summary form only given. A carbon nanotubes-deposited flexible film was prepared by electrophoretic method. A polyimide film coated with Titanium was used as a cathode and a stainless steel plate as an anode, respectively. The two electrodes were placed into a bath with solvent consisting of fine carbon nanotubes particles, Mg(NO3)2 6H2O and isopropylalcohol (IPA). Mixed solution was stirred for about 2-4 hours to assure the complete dissolution of Mg(NO3)2 6H2O and the dispersion of carbon nanotubes particles. DC electric field was applied to the two electrodes. The anode voltage was about 100V. After 1-2 minutes, the carbon nanotubes particles were deposited on the polyimide film coated with Titanium. The electron field emission properties of the prepared thin film were tested by a diode mechanism. The turn-on field of the flexible film was about 2.96V/μm. The current density of the flexible film was about 200μA/cm2 at an electric field of 5.9V/μm. The morphology and structure of the carbon nanotubes-deposited flexible film were examined by scanning electron microscope (SEM) and Raman spectroscopy. The experimental results indicate that this film could be a promising material applicable to cold cathodes.
