Micrograph 565 and full record
- Micrograph no
- 565
- Brief description
- Vapour-grown carbon nanotubes
- Keywords
- carbon, carbon nanotube, chemical vapour deposition (CVD), ferrocene, nanotube , polymer
- Categories
- Ceramic, Polymer
- System
- Carbon nanotube
- Composition
- Not specified
- Standard codes
- Reaction
- Processing
- These fibres grow in the heated zone during chemical vapour deposition, using a fine solution of ferrocene dissolved in toluene
- Applications
- Carbon nanotubes may be considered a high performance mechanical polymer or an electrically conducting polymer but have potential uses in nanodevices, sensors, hydrogen storage and fuel cells
- Sample preparation
- The specimen has been sputter-coated with gold to avoid charging in the SEM
- Technique
- Scanning electron microscopy (SEM)
- Length bar
- 5 μm
- Further information
- Chemical vapour deposition (CVD) allows the synthesis of high purity nanotubes of controlled length and diameter. The nanotubes in this specimen were formed in the heated zone of the apparatus whilst using ferrocene dissolved in toluene. The fibres are of high purity and their diameters range from 400 to 500 nm.
