KATALYTISCHER WASSERLÖSLICHER POLYMERER FILM FÜR METALLBESCHICHTUNGEN

摘要

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/m2 copper, is useful as backing for wallpaper which can provide effective far-field shielding of electromagnetic radiation.
