Using Plasma Metallisation for Manufacture of Textile Screens Against Electromagnetic Fields

Abstract

In this study, a method of the metallisation of polypropylene (PP) nonwovens is presented.The influence of power dissipated in the target on the efficiency of screening a flat electromagnetic wave is discussed. Fabric metallisation was carried out using the standard magnetron sputtering process of Zn-Bi metal targets in argon ambient. A pulse current source with a changing group frequency was used for powering the target. The metallic layers obtained were characterised by good adhesion to PP, with a screening efficiency approaching 45 dB.
