Functional Applications of AZO Multilayer and AZO Single Layer Thin Films: EMI Shielding, Antibacterial Activity, hydrophobic properties, and Water and Acid Water Resistance
Abstract:
The Al (3 at%)-doped ZnO (AZO)/Ag/AZO multi-layer films annealed at 100 oC for 20 min under oxygen atmosphere were studied for the simultaneous realization of the electromagnetic interference (EMI) shielding and the antibacterial activity for the transparent glass panel applications. The annealed AZO (45 nm)/Ag (9 nm)/AZO (45 nm)/glass multi-layer films showed a high EMI shielding effectiveness of approximately 39 dB and a strong antibacterial activity for Escherichia coli and Staphylococcus auraus at the same time. They showed hydrophobic properties by a simple thermal annealing at 100 oC for 20 min under an oxygen atmosphere.
