Abstract
The present disclosure is directed to methods for altering the surface of carbon fibers by growing carbon nanotubes thereon. Coverage of the carbon fibers by carbon nanotubes provides increased surface area and aspect ratio, as well as provides high electrical and thermal conductivity. In some embodiments, the surface of the carbon fibers are further modified via argon-ion bombardment or plasma treatment to provide controllable defects and to allow for easier growth of carbon nanotubes on the surface of the carbon fibers.
