Özet

© 2021 The Textile Institute.The widespread use of electronic devices leads to Electromagnetic Interference (EMI), which reduces equipment's performance and even threatens human health. Consequently, attempts have been made to develop shields against EMI using magnetic and conductive components. In this study, one of the most industrially prominent polypropylene (PP) nonwoven was converted to an EMI shield through the deposition of conductive polyaniline (PAn) and various magnetic (nano)particles (MPs), such as Fe3O4, CoFe2O4, and MnFe2O4. The preparation of PP composite was ensured by polymerization of the aniline in the presence of different MPs impregnated-PP fabrics. The MPs' crystal structures and magnetic properties, and morphological changes of the PP were revealed by XRD, Vibrating Sample Magnetometer (VSM), and SEM techniques. The EMI shielding property of the fabrics was examined within 30 MHz-3 GHz. Accordingly, the double-coated PP/MnFe2O4/PAn composite showed the highest absorption-dominant attenuation (94.2% at 2.11 GHz) with a 12.4 dB EMSE value.
