Studies on Electromagnetic Shielding Effectiveness of Electrically Conductive Fabric

Due to rapid growth of the electronic industry and the widespread use of electronic equipments have led to many electromagnetic interference (EMI) problems like malfunctioning of an electrical circuit and the possibility of cancer. This can be prevented using electromagnetic shielding. Use of textiles as a shielding material gives an advantages of light weight and flexibility as compared to metal screens and the other traditional shielding materials. Many researchers have tried different methods to make textile material electrically conductive for electromagnetic shielding use. PC fabric was made electrically conductive by silver coating of different thickness using plasma technique and electromagnetic shielding effectiveness has been investigated in the present paper. It was observed that with increase in coating thickness, better shielding effectiveness is achieved.
