CORRELATIVE AND COVARIANCE ANALYSIS OF THE ELECTROCONDUCTIVE FABRICS

Abstract

This paper presents the correlation and covariance analysis of the electrical resistance dependence of mass, thickness and air permeability of textile structures coated with magneto-conductive materials and used for protection against electromagnetic waves. For this scientific approach, 9 experimental models of compositesbased fabrics with electroconductive properties were made by applying different pastes based on organic polymeric matrices polyvinyl alcohol (PVA), copper (Cu), aluminium (Al), zinc (Zn), iron oxide (Fe3O4) and polypyrrole (PPY) solution using a classical deposition method such as scraping. The surface resistance was evaluated using a resistance meter device based on two parallel electrodes. From all samples analysed 5 samples based PPY, PVA-Ni, PVA–Ni-Al and PVA-Zn present a surface resistance between 103 and 105 Ω. Because the surface resistance has a lower value this means that the samples have a good conductivity to be used as layers for electromagnetic shielding systems.
