摘要

This paper concerns multilayer, shielding textile-polymeric materials with a high shielding effectiveness. This effectiveness results first of all from their high capability to absorb electromagnetic radiation. (EMR) brought about to a large extent by the intensification of multiple internal reflections at the boundaries between the layers of component materials. These new shielding materials are characterised by low thicknesses and surface weights, amounting to 1.0 - 2.0 mm and 90 - 400 g/m~2, respectively, depending on their structures. Such materials with various structures, containing various functional particles, meet high requirements of EMR shielding effectiveness within the frequency range tested from 8.0 to 18.0 GHz. Their coefficient of EMR absorption is at a level of ≥40%, and in some structures it even exceeds 70%, while the reflection coefficient is ≤20% and that of transmission amounts to ≤40%, approaching even 1%.
