Composites based on segregated semi-IPТі containing carbon nanotubes and microparticles of metallic nickel up to 3% by weight have a screening efficiency of up to 25 dB. Composites based on organo-inorganic polymer and carbon nanotubes or hybrid filler (10 vol% with a fraction of BNT 3 vol%) as well as systems with segregated distribution of filler in thermoplastic polyethylene provide screening efficiency of 24.3 dB with increased absorption due to multiple reflection of the electromagnetic wave in the segregated structure of polymer and/or filler. Thin films (up to 100 mkm) of polyimide-containing nanocomposites containing carbon nanotubes up to 5 wt. % thermostable over 400°C have a low reflection coefficient and can be used in the formation of multilayer protective coatings.
