Patent ID: 8247036

Claim:
A method for making a coaxial cable, the method comprising the steps of: (a) providing a carbon nanotube structure comprising a plurality of carbon nanotubes; and forming: (b) at least one conductive coating on the plurality of carbon nanotubes of the carbon nanotube structure, and a strengthening layer surrounding the at least one conductive coating by immersing the carbon nanotube structure with the at least one conductive coating applied to the plurality of carbon nanotubes in a container of liquid polymer, such that the entire surface of the plurality of carbon nanotubes of the carbon nanotube structure are soaked with the liquid polymer, and curing the liquid polymer; (c) a carbon nanotube wire structure from the carbon nanotubes with the at least one conductive coating and the strengthening layer; (d) at least one layer of insulating material on the carbon nanotube wire structure; (e) at least one layer of shielding material on the at least one layer of insulating material; and (f) at least one layer of sheathing material on the at least one layer of shielding material.
