  Several shielding applications, to protect human health and electronic
devices against dangerous effects of electromagnetic radiation, require
solutions that fabrics can suitably fulfill. Here, we will investigate the
electromagnetic interference shielding effectiveness of polypyrrole-coated
polyester textiles, in the frequency range 100-1000 MHz. Insertion losses for
several conductive fabrics with different surface resistivity ranging from 40
Ohm till the very low value of 3 Ohm were evaluated with a dual-tem cell.
Correlations between the shielding effectiveness and the conductivity of
composites are also discussed.
