US Patent 7449631 - CNT shielding layer for coaxial cable

This patent from Hon Hai Precision teaches using carbon nanotube yarn as electromagnetic shielding for coaxial cable which has the potential for increasing cable yield at reduced cost in comparison with previous materials. Claim 1 reads:

1. A coaxial cable comprising:

at least one conducting wire;

at least one insulating layer, each insulating layer is located about a corresponding conducting wire;

at least one shielding layer surrounding the at least one insulating layer, each shielding layer comprising a plurality of carbon nanotube yarns; and

a sheath wrapping the at least one shielding layer.
