Fabrication of carbon nanotubes field emission cathode by composite plating.
Carbon nanotubes (CNTs) have high aspect ratio and have great potential to be applied as the field emission cathode because of its large field enhancement factor. In this work, a high performance carbon nanotube field emission cathode (CNTFC) was fabricated by using a composite plating method. The CNTs were purified by acid solutions and then dispersed in electrobath with nickel ions at tempera...
متن کاملAdapting carbon nanotubes for fine composite structures
Although defective, commercially-available, CVDgrown, multi-walled carbon nanotubes are widely used for polymer nanocomposites due to their availability and low cost. However, to use these materials effectively, they must be disentangled, and chemically modified in order to produce high quality composites. This paper shows that such nanotubes can be disentangled by cutting; abrupt, repeated exp...
متن کاملInfluence of Carbon Nanotubes Dispersion on Thermal Properties of Copper-Carbon Nanotubes (CNTs) Composite Materials
In this present work, two methods for dispersing carbon nanotubes into the copper matrix were tested: a Solid Route process where CNTs are simply mixed with the copper powder and a Liquid Route process where CNTs are dispersed in a copper salt solution and then mixed with the metallic copper powder. Powders are sintered by uni-axial hot pressing process under vacuum atmosphere at 650°C and ther...
متن کاملCarbon Capture Using Amine-modified Carbon Nanotubes
The increasing rise in the rate of both anthropogenic CO2 emissions and atmospheric CO2 concentration, combined with an evolving understanding of what this means for global climate change both now, and in the future, has increased the need for novel technologies for CO2 capture from large point sources. Current industry standards involve the use of amine solvents, which have a large parasitic l...
متن کاملDispersion of Carbon Nanotubes: Mixing, Sonication, Stabilization, and Composite Properties
Advances in functionality and reliability of carbon nanotube (CNT) composite materials require careful formulation of processing methods to ultimately realize the desired properties. To date, controlled dispersion of CNTs in a solution or a composite matrix remains a challenge, due to the strong van der Waals binding energies associated with the CNT aggregates. There is also insufficiently defi...
