Abstract

Electromagnetic shielding (EM) achieved by flexible materials has gained an increased significance in today’s radiation polluted environment. In order to obtain electromagnetic shielding fabrics, two main technologies are available: insertion of conductive fibers/yarns and coating with conductive films. This paper focuses on manufacturing and investigation of EM shielding fabrics achieved by combining both technologies: fabrics with inserted conductive yarns of stainless steel and silver were coated with a thin copper film obtained by magnetron sputtering. Scanning Electron Microscopy (SEM) and atomic absorption spectroscopy measurements evidenced the copper content while electromagnetic shielding tests by means of Transversal Electromagnetic (TEM) cell evidenced good shielding effectiveness of 20-35 dB within 0.1-1000 MHz frequency range.

Keywords: Fabrics, copper thin films, conductive yarns, shielding effectiveness
