Abstract

A method of forming an array of aligned, uniform-length carbon nanotubes on a planar surface of a substrate employing a composite catalyst layer of iron and cobalt. The carbon nanotubes have visible length and are useful for producing spun threads of carbon nanotubes having improved spinability and mechanical and electrical properties.
