http://www.freepatentsonline.com/7459627.html

This patent from Hon Hai Precision and Tsinghua University is similar to an earlier patent (US Patent 7449631) and extends the scope of protection to using carbon nanotubes as electromagnetic shielding for coaxial cables.

1. A coaxial cable comprising:

at least one conducting wire;

at least one insulating layer, each insulating layer being respectively coated on a corresponding conducting wire;

at least one shielding layer surrounding the at least one insulating layer, each shielding layer comprises one or more carbon nanotube films; and

a sheath wrapping the at least one shielding layer.
