Ultra-pure single wall carbon nanotube fibres continuously spun without promoter

We report a new strategy towards the control of carbon nanotube (CNT) structure and continuous fibre formation using a floating catalyst direct spinning CVD process. In the procedures used to date, a sulphur promoter precursor is added to significantly enhance the rate of CNT formation in the floating catalyst synthesis. Within the reaction zone, the rapidly grown nanotubes self-assemble into b...

Strong carbon-nanotube fibers spun from long carbon-nanotube arrays.

The superior mechanical properties of carbon nanotubes (CNTs) mean they have been regarded as a new material with the potential to revolutionize and enable many advanced technologies. CNTs have extremely high tensile strength ( 150 GPa), high modulus ( 1 TPa), large aspect ratio, low density, good chemical and environmental stability, and high thermal and electrical conductivity. These superior...

Novel polygonized single-wall carbon nanotube bundles.

We have synthesized novel crystalline ropes of "polygonized" single-wall carbon nanotubes (SWCNTs). The tubes exhibit rounded-hexagonal cross sections in contrast to the earlier observations of nearly circular tubes. To investigate the structural characteristics of the lattice of SWCNTs we have performed extensive molecular-dynamics simulations. We find several metastable structures of the latt...

Formation of Single-Wall Carbon Nanotube Superbundles

Since their discovery in 1993,1,2 carbon single-wall nanotubes (SWNTs) have been of great interest because of their expected novel electronic,3 mechanical,4 and gas adsorption properties.5 Difficulties arise in measuring these various properties because the SWNTs currently available for analyses have very small bundle sizes (1020 nm) and are typically in random orientations. A vital step for th...

Photoconductivity in single wall carbon nanotube sheets

In this paper we report for the first time, the photoconductivity of large area sheets of single wall carbon nanotube upon laser illumination. The photoconductivity exhibited an increase, decrease or even ‘negative’ values when the laser spot was on different positions between contact electrodes, showing a ‘position’ dependent effect of photoconductivity. Photon induced charge carrier generatio...
