Effects of binders and organic vehicles on the emission properties of carbon nanotube paste

The different inorganic binders and organic vehicles were used to synthesize carbon nanotube (CNT) paste for field emission display. The morphologies, thermal and emission properties of the CNT paste with different components were investigated. The uniformity, the adhesion, and emission properties of CNT paste was improved when an inorganic binder changed from a glass frit to spin on glass (SOG). The current density increases by 5 times in magnitude when the ethyl cellulose solution was used instead of to acryl solution. The fabricated CNT emitter using photosensitive CNT paste showed high brightness of 18,000 cd/m2 at low operating voltage of 1200 V.
