1. A continuous CNT infusion process comprising:

  • disposing a barrier coating and a carbon nanotube (CNT)-forming catalyst on a surface of a metal fiber material of spoolable dimensions;

    wherein the barrier coating is selected from the group consisting of an alkoxysilane, a methylsiloxane, an alumoxane, alumina nanoparticles, spin on glass and glass nanoparticles; and

    synthesizing carbon nanotubes on said metal fiber material by exposing the metal fiber material to carbon nanotube growth conditions, thereby forming a carbon nanotube-infused metal fiber material;

    wherein the metal fiber material is moving while disposing the barrier coating and the CNT-forming catalyst, and while synthesizing the carbon nanotubes.
