Activation of Carbon Nanotube Emitters by Using Supercritical Carbon Dioxide Fluids with Propyl Alcohol

Abstract: This paper explores the application of supercritical carbon dioxide fluids on the field emission enhancement for vertically aligned carbon nanotubes. The typical heating process cannot effectively activate the deionized-water-rinsed carbon nanotube emitters, exhibiting poorer field emission performance, due to residual moisture uptake in the carbon nanotubes. In contrast, the field emission enhancement can be achieved significantly by applying the supercritical carbon dioxide fluids associated with 3 to 9 vol … Show more

“…CNT, which are graphite sheets rolled into circular bundles, have been researched extensively as filler in MMMs due to their ideal properties [27][28][29][30][31] with both single-walled (SW) and multi-walled (MW) versions of CNT being utilised [3,10,15,32,33]. Their extraordinary mechanical and electrical properties nominate their use as a filler to reinforce the structure of the polymer matrix or to increase the electrical conductivity of the composite materials.…”

“…The SCCO 2 fluid has liquidlike property that allows it to carry H 2 O molecules. Additionally, it also has gaslike and high-pressure properties to diffuse efficiently into nanoscale structures without any damage [11]. Thus, these striking advantages are employed to oxidize the thin film and to fabricate nanostructures at low temperature.…”
