US Patent 7399794 - Ionization resistance using CNT polymer composite

This patent from the University of South Florida teaches the use of carbon nanotube composites for space shielding. Claim 1 reads:

1. A method for resisting ionizing radiation comprising:

(a) providing a device that is subjected to ionizing radiation when in use, wherein the device comprises a transparent polymer and a plurality of carbon nanotubes at least on the device's surface, wherein the carbon nanotubes are incorporated into the matrix of the polymer; and

(b) exposing the device to ionizing radiation, whereby the device exhibits improved resistance to ionizing radiation.

One possibly relevant earlier patent is US 6,265,466 teaching a nanotube/polymer composite forming an electromagnetic interference shield.
