摘要

The present work concerns the evaluation of emitting multiwall carbon nanotube (MWCNT temperature, here referred to as "emission point" temperature. The latter is related to the onset o thermal degradation of polymer molecules neighboring to the MWCNT. The investigation methoi combines the registration of both current voltage characteristics and thermal degradation volatil products for "polymer-MWCNT" composite emitter during the emitting process. Our experimenta setup involves a time-of-flight mass spectrometer and field emission unit.
