توسعه و بررسی پارچه های محافظ الکترومغناطیسی با مواد افزودنی هدایت الکتریکی مختلف

This study presents technological guidelines for designing coated textile fabrics, which are able to safeguard high electrostatic charge dissipation properties and to provide effective protection against EMR, using two types of electrically conductive coatings. The results of EMR shielding measurements, especially within the range of 2 GHz–20 GHz, showed that fabrics with conductive coatings exhibit certain advantages over fabrics with incorporated metalized yarns. Whereas shielding properties at the low frequency range of 20 kHz–50 kHz for all investigated conductive fabrics are similar despite the type of conductive additive. Methods for measurement of electrostatic properties, reflection and transmission as well as the assessment of EMR shielding effectiveness (SE) are also presented.
