Transparent conductive multilayer films on flexible substrate for electric field shielding application

摘要

Several thin transparent and conductive films composed of conductive oxides (ITO) and metallic ultrathin layers (Ag, Au, Ti) have been deposited on flexible polycarbonate substrate and characterized in terms of optical transmittance, electrical conductivity and electric field screening efficiency. Thin films properties were evaluated with respect to the requirement concerning conductive garments described in Standard IEC 60895 "Live working-Conductive clothing" for workers operating on High Voltage or Ultra High Voltage live lines. Results show that the investigated multilayers could be adopted as facial masks for protection of workers from drift currents and electric field exposure, offering better alternative in electric performances and wearing comfort than previously tested metallic nets.
