Resumen:
Highly ordered mesoporous ZrO2 thin films were prepared by evaporation induced self-assembly. Complexing agents and low pH were simultaneously employed in order to control the hydrolysis?condensation kinetics, permitting to cast films in one step. Many commercially available PPO-based surfactants can be used as templates, yielding different pore sizes. The mesoporosity is well preserved at high temperatures (600 C) and after exposing the films to extreme alkaline conditions (1 M NaOH, 18 h). The procedure has been used to cast multilayer films, paving the way to mesoporous thin films-based UV photonics.
