High-yield growth of vertically aligned carbon nanotubes on a continuously moving substrate.
Vertically aligned carbon nanotube (CNT) arrays are grown on a moving substrate, demonstrating continuous growth of nanoscale materials with long-range order. A cold-wall chamber with an oscillating moving platform is used to locally heat a silicon growth substrate coated with an Fe/Al2O3 catalyst film for CNT growth via chemical vapor deposition. The reactant gases are introduced over the subs...
متن کاملACCVD Growth of Vertically Aligned Single-Walled Carbon Nanotubes on a Quartz Substrate
Vertically aligned single-walled carbon nanotubes (SWNTs) up to 5 microns thick as shown in Fig 1 were produced by an alcohol CVD process [1]. In contrast to the first report of CVD growth of vertically aligned SWNTs [2], hydrogen gas was supplied only during the heating-up stage with the improved background vacuum condition. A time-progressive investigation of the growth process was studied by...
متن کاملGrowth Process of Vertically Aligned Single-walled Carbon Nanotubes
The growth process of vertically aligned single-walled carbon nanotube (SWNT) films was investigated by means of in situ optical analysis and scanning electron microscopy. The measurements reveal that the growth of the SWNT film decreases after longer reaction times. This decrease is attributed to a combination of a diminishing growth rate and burning of the SWNTs due to oxygen in the growth ch...
متن کاملHigh-rate low-temperature growth of vertically aligned carbon nanotubes.
We report the low-temperature growth of vertically aligned carbon nanotubes (CNTs) at high growth rates by a photo-thermal chemical vapour deposition (PTCVD) technique using a Ti/Fe bilayer film as the catalyst. The bulk growth temperature of the substrate is as low as 370 °C and the growth rate is up to 1.3 µm min(-1), at least eight times faster than the values reported by traditional thermal...
متن کاملMembranes of vertically aligned superlong carbon nanotubes.
In the present work, we have developed a simple but effective method to prepare superlong vertically aligned carbon nanotubes (SLVA-CNT) and epoxy composite membranes, and we have demonstrated that various liquids, including water, hexane, and dodecane, can effectively pass through the SLVA-CNT membranes. These results were confirmed by molecular dynamics simulations. While the mechanical densi...
