OBJECTIVES
To induce structuration effects on thin films through a liquid solution route
To induce structuration effects on thin films through a liquid solution route
Highlight
The deposition of nanospheres (e.g. polystyrene) followed by i/ their impregnation with a solution arising from sol-gel and/or hydrothermal synthesis approaches, and ii/ their subsequent elimination, leads to structured oxide thin films of enhanced roughness while preserving a high optical quality of the film.
The synergy between natural wettability properties and roughness effects enables to enhance the natural superhydrophilicity persistence of nano-composite TiO2-SiO2 films, or to propose a simple approach to produce superhydrophobic films trough a non-fluorinated sol-gel route.
