Abstract
Large-pore TiO2 and ZrO2 mesoporous films with 2D-Hex or cubic mesostructures were prepared by dip-coating. Organic bifunctional molecules presenting an organic function and a complexing grafting group (phosphate, carboxylate) were explored as surface modifiers. The incorporation of these functions into the mesoporous network was monitored by crossed FT-IR and EDS techniques. Leaching experiments in different conditions were performed to assess the anchoring of the grafted groups. While phosphate or phosphonate groups are strongly grafted, carboxylate functions can be released in a pH-dependent way.
