FIELD: physics.
SUBSTANCE: invention relates to means of reducing the level of electromagnetic radiation and can be used in various industries to reduce the level of both electromagnetic radiation and radio-frequency interference. Described is a screening film comprising a polymer and carbon nanotubes distributed therein, the polymer being polyvinylidene fluoride, and the carbon nanotubes being single-walled and contained in amount of 0.01–10 wt%, where the film additionally contains a solvent selected from a series of ethylene carbonate, propylene carbonate, and the ratio of length to diameter of carbon nanotubes is not less than 3,000. Also described is a method of producing a screening film.
EFFECT: high ability of screening from electromagnetic radiation and strength.
