Stable and high emission current from carbon nanotube paste with spin on glass

A carbon nanotube (CNT) paste was synthesized by mixing multiwalled CNTs (MWNTs), organic vehicles, and inorganic binder. The paste with spin on glass (SOG) showed improved uniformity, dispersion, and adhesion characteristics of the CNT paste layer. The emission characteristics of CNT paste with SOG...

Description
Summary:A carbon nanotube (CNT) paste was synthesized by mixing multiwalled CNTs (MWNTs), organic vehicles, and inorganic binder. The paste with spin on glass (SOG) showed improved uniformity, dispersion, and adhesion characteristics of the CNT paste layer. The emission characteristics of CNT paste with SOG were improved, and compared to those of a CNT paste with a glass frit. When the organic vehicle was changed from ethyl cellulose to acryl solution, current density of CNT paste increased. The firing condition for CNT pastes was investigated and optimized. It was found that firing at 450 °C under N 2 was the most suitable condition for pastes with MWNTs. We obtained stable and high emission current of 100 mA at an electric field of 8.35 V ∕ μ m from CNT paste with SOG printed on a Ni plate.
