Large area screen-printing cathode of CNT for FED

We developed a new MWNTs paste by mixing with oxide-conductive powders for screen-printing. Optimum density and length of CNTs were got after purifying process. Rapid sintering processing (RSP) was adopted for fixing CNT to substrate and removing organic binding material. CNTs were exposed to erect...

Summary:We developed a new MWNTs paste by mixing with oxide-conductive powders for screen-printing. Optimum density and length of CNTs were got after purifying process. Rapid sintering processing (RSP) was adopted for fixing CNT to substrate and removing organic binding material. CNTs were exposed to erect on the surface by developing multi-step post-treatment. Large area cathode (>5 inch) of carbon nanotubes was fabricated using screen-printing. The good cathode of emission uniformity property was obtained. The current density is 35 mA/mm 2 at the electric field 2.5 V/μm. The turn-on field of CNTs is approximately 2.0 V/μm. Therefore, the cathode is suitable for FED.
