Glass substrates having carbon nanotubes grown thereon and methods for production thereof

A carbon nanotube growth process comprising:

• depositing a catalyst precursor on a glass fiber substrate, the catalyst precursor being deposited from a solution comprising water as a solvent;
• wherein the catalyst precursor is formed from a reaction between at least one transition metal salt and hydrogen peroxide in the solution from which the catalyst precursor is deposited;
• converting the catalyst precursor into a catalyst that is operable for forming carbon nanotubes when exposed to carbon nanotube growth conditions;
• and
• exposing the glass fiber substrate to carbon nanotube growth conditions while the glass fiber substrate is being transported so as to grow carbon nanotubes thereon.

A carbon nanotube growth process comprising:

• allowing a solution comprising water, hydrogen peroxide, an iron (II) salt or a hydrate thereof, and a cobalt (II) salt or a hydrate thereof to form a catalyst precursor in the solution, the solution comprising water as a solvent;
• depositing the solution with the catalyst precursor therein onto a glass fiber substrate;
• converting the catalyst precursor into a catalyst that is operable for forming carbon nanotubes upon exposure to carbon nanotube growth conditions;
• and
• exposing the glass fiber substrate to carbon nanotube growth conditions so as to grow carbon nanotubes thereon.
