Abstract:

This paper presents the results of studies carried out at the Textile Research Institute in Łódź, aimed at developing multi-layer, flat or spatial textile-polymeric materials, designed for shielding electromagnetic radiation (EMR), showing a possible high absorption coefficient, a so-called insertion loss of ≥ 40%. These materials were designed by the method presented in our previous paper [1], which consists in bonding/laminating component coating materials with diversified permittivity and magnetic permeability into multi-layer systems. Multi-layer shielding materials designed and made according to such assumptions are characterised by a predominant EMR absorption capability, considerably higher than their EMR reflection capability; they also show a low surface density, elasticity and ease of storage and transport. The positive test results of shielding effectiveness obtained, within a wide range of frequency (0.8 – 18 GHz), for the newly developed shielding materials offers real prospects for their practical use in various fields of the economy.
