Brief description
Aligned array of nanotubes
Keywords
alignment, array, carbon, carbon nanotube, chemical vapour deposition (CVD), ferrocene, film, nanotube Link to MATTER Glossary entry for nanotube, order, polymer Link to MATTER Glossary entry for polymer, quartz
Categories
Ceramic, Polymer
System
Carbon nanotube
Composition
Not specified
Standard codes
Reaction
Processing
Chemical vapour deposition onto a quartz substrate, using a fine solution of ferrocene dissolved in toluene
Applications
Such architectures may be of interest as nanocomposites for use in nanodevices. More generally, carbon nanotubes may be used for hydrogen storage or for fuel cell applications
Sample preparation
The specimen has been sputter-coated with gold to avoid charging in the SEM
Technique
Scanning electron microscopy (SEM)
Length bar
25 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 deposited on quartz using ferrocene dissolved in toluene. They are approximately 40 nm in diameter and 60 microns long.
