Abstract
Electromagnetic radiation shielding textile material comprising metal-coated fabric adapted to be applied with overlapping seams at least 4 cm wide to provide at least 80 dB of far-field shielding against electromagnetic radiation between 0.1 and 10 gigahertz. Fabric, e.g. non-woven nylon fabric, coated with at least one layer of electrolessly-deposited metal, e.g. at least 15 g/m.sup.2 copper, is useful as backing for wallpaper which can provide effective far-field shielding of electromagnetic radiation.
Claims7
Electromagnetic radiation shielding textile material comprising metal-coated fabric having a uniform coating of an electrolessly deposited metal about 0.5 to 5 micrometers thick wherein, when strips of said fabric are joined with overlapping seams about 4 cm wide, said fabric provides at least 80 dB of far-field shielding against electromagnetic radiation between 0.1 and 10 gigahertz when tested in accordance with MIL-STD-285 using a 60.times.60 cm port.
Wallpaper effective for far-field shielding of electromagnetic radiation between 0.1 and 10 gigahertz having as a backing metal-coated non-woven fabric, uniformly coated with at least one layer of electrolessly-deposited metal about 0.5 to 5 micrometers thick;
- wherein, when strips of said wallpaper joined using wallpaper paste with overlapping seams about 4 cm wide is tested in accordance with MIL-STD-285 using a 60.times.60 cm port, said wallpaper exhibits at least 80 dB far field shielding against electromagnetic radiation between 0.1 and 10 gigahertz.
