We report the optimisation of the experimental variables for the synthesis of large-area
(90 cm2), mm-thick carpets of vertically aligned multi-wall carbon nanotubes (MWCNTs)
using the aerosol-assisted chemical vapour deposition technique. The effect of the reactor
size, temperature, time and the flow rate of the carrier gas on the catalytic conversion rate
of the precursor, composition of the atmosphere of the reactor and various properties of
MWCNTs such as the mass, length, outer diameter, defect density, oxidation resistance
and residual catalyst concentration was investigated. By increasing the volume of the reactor
from around 0.2 to 8.5 L, the mass of synthesised MWCNTs and the efficiency of the precursor
were increased fivefold (up to 14 g/h.) and twice (up to 88%), respectively. Freestanding
and on-substrate carpets of MWCNTs could withstand normal handling without
falling apart, making them suitable for characterisations and applications from nano to
macro scales. The synthesis recipe also improved the production rate of nitrogen-containing
MWCNTs by an order of magnitude.
