Abstract
Methods for growing carbon nanotubes on glass substrates, particularly glass fiber substrates, are described herein. The methods can include depositing a catalytic material or a catalyst precursor on a glass substrate; depositing a non-catalytic material on the glass substrate prior to, after, or concurrently with the catalytic material or catalyst precursor; and exposing the glass substrate to carbon nanotube growth conditions so as to grow carbon nanotubes thereon. The glass substrate, particularly a glass fiber substrate, can be transported while the carbon nanotubes are being grown thereon. Catalyst precursors can be converted into a catalyst when exposed to carbon nanotube growth conditions. The catalytic material or catalyst precursor and the non-catalytic material can be deposited from a solution containing water as a solvent. Illustrative deposition techniques include, for example, spray coating and dip coating.
