US Patent 7476889 - Radiation protective clothing using nanomaterials

US Patent 7,476,889

This patent assigned to Meridian Research and Development with priority possibly going back as far as 1998 (via continuations-in-part) includes some very basic claims to using nanomaterial/polymer composites in clothing for radiation protection. Claim 1 reads:

1. An article of clothing comprising a flexible layer formed from a radiopaque polymeric mixture having a polymer and a radiopaque nano-material.

Although this may not be prior art a patent to Eikos teaches using carbon nanotubes in EMI shielding polymers has priority to 1999 (US Patent 6,265,466).
