Multi-Functional Nanoscaled Film Deposited on PET Non-Woven by Sputtering
In order to prepare a time decay-resistant electromagnetic shielding (ES) fabric with good handle, moisture permeability and antibacterial properties, Cu, Ag, Ag/Cu and Ag/Cu/Ag films were deposited on PET non-woven by sputtering in screening experiment. Considering the post continues processing, this study focuses on discharge parameters optimum for a limited short time. Relationship was studied between deposited rate and ES effectiveness (ESE) for the four metallic films on various substrates. The metal deposit greatly relays on the chemical nature of the substrate and target metal category. The deposited metal rate on metal is larger than that on PET. In comparison with single metallic film, the dB value of multi-metallic film obtained for same time even for more time remarkably dropped. Therefore, an Ag-coated PET no-woven was finally fabricated as the multi-functional fabric with anti-decay ESE. The multi-functional PET no-woven with good handle obtained for 3min. by optimizing other parameters exhibits higher ESE, good anti-bacterial and moisture permeability.
