Comparative Performance of Copper and Silver Coated Stretchable Fabrics
Azam Ali,Vijay Baheti,Jiri Militky,Zaman Khan,Syed Qummer Zia Gilani 한국섬유공학회 2018 Fibers and polymers Vol.19 No.3
The present work described the development of multifunctional, electrically conductive and durable fabrics by coating of silver and copper particles using a dipping- drying method. The particles were directly grown on fabric structure to form electrically conductive fibers. Particles were found to fill the spaces between the microfibers, and were stacked together to form networks with high electrical conductivity. The electrically conductive fabrics showed low resistance with high stretch ability. The utility of conductive fabrics was analyzed for electromagnetic shielding ability over frequency range of 30 MHz to 1.5 GHz. The EMI shielding was found to increase with increase in concentration of copper and silver particles. Furthermore, the heating performance of the copper and silver coated fabric was studied through measuring the change in temperature at the surface of the fabric while applying a voltage difference across the fabric. The maximum temperature (119 oC for silver and 112 oC for copper) were obtained when the applied voltage was 10 V. Moreover, the role of deposited particles on antibacterial properties was examined against pathogenic bacteria such as Staphylococcus aureus and Escherichia coli. At the end, the durability of coated fabrics was examined against several washing cycles. The fabrics showed good retention of the particles, proved by small loss in the conductivity of the material after washing.
