Multi-functional TiO2/Si/Ag(Cr)/TiNx coatings for low-emissivity and hydrophilic applications

- Multi-functional thin films were deposited by RF and DC magnetron sputtering.
- High visible transmittance (∼85.5% at 550 nm) was achieved with low-e value 0.067.
- Different bandgap concept was used to improve the hydrophilic properties.
- Transparent, superhydropbilic films with water contact angle ∼5° were achieved.
