FIELD: physics.
SUBSTANCE: invention describes material which screens electromagnetic waves and a sheet which uses said material. The invention also describes electromagnetic wave screening material in gel state, which contains an ionic liquid which contains an anion selected from a group comprising phosphate, having different valency and borate and in which fine particles are distributed, where the said particles can reflect, suppress and absorb electromagnetic waves.
EFFECT: electromagnetic wave screening material can provide high capacity of screening electromagnetic noise and flexibility when used in form of a sheet, and can provide fire- and heat-resistance in certain applications.
