Abstract

Electromagnetic Interference Shielding (EMI) shields have become more important because of the detrimental effects EMI has on systems, equipment, and even human health. High yields of conductive polypyrrole and magnetic (nano)particles (MPs) were consecutively placed on PET nonwoven to highlight this challenge. Surface resistance was measured to identify the influence of polymerization factors including oxidant content and MP deposition order. The MPs' magnetic properties and morphology were examined using Vibrating Sample Magnetometer (VSM) and Scanning Electron Microscopy (SEM). The electromagnetic shielding effectiveness (EMSE) and the relative shielding effectiveness (Re) and absorption (Ab) within the 30 MHz-3 GHz range were used to assess the textiles' EMI shielding properties. Accordingly, the most considerable absorption-dominant attenuation (74.7% at 2.20 GHz) and maximum EMSE value (6.60 dB) were found in the PET/PPy/Fe3O4 composite.
