CNT-infused metal fiber materials and process therefor

摘要

A composition includes a carbon nanotube (CNT)-infused metal fiber material which includes a metal fiber material of spoolable dimensions, a barrier coating conformally disposed about the metal fiber material, and carbon nanotubes (CNTs) infused to the metal fiber material. A continuous CNT infusion process includes: (a) disposing a barrier coating and a carbon nanotube (CNT)-forming catalyst on a surface of a metal fiber material of spoolable dimensions; and (b) synthesizing carbon nanotubes on the metal fiber material, thereby forming a carbon nanotube-infused metal fiber material.

1. A composition comprising a carbon nanotube (CNT)-infused metal fiber material comprising:
a metal fiber material of spoolable dimensions; carbon nanotubes (CNTs) infused to said metal fiber material by growing the CNTs in the presence of transition metal nanoparticles;
wherein said CNTs are uniform in length and uniform in distribution; and a barrier coating conformally disposed about the metal fiber material, the barrier coating separating the metal fiber material from transition metal nanoparticles used for growing the CNTs;
wherein the barrier coating is selected from the group consisting of an alkoxysilane, an alumoxane, spin on glass, and glass nanoparticles.
