This work dealt with the synthesis and characterization of mesoporous silica thin films. The synthesis uses the surfactant self-assembly route in order to template a silica gel. Hybrid thin films presenting a high degree of organization at the nanometer scale are obtained. Then the surfactant removal leads to materials of organized and tailored porosities and of large surface areas.Different synthesis parameters have been investigated. In situ measurements carried out by X ray Reflectivity (XR) and Grazing Incidence Small Angle X-ray Scattering (GISAXS) have evidenced the major role played by the relative humidity. Some surfactant removal methods by ethanol rinsing have also been tested, with the intent to empty the mesopores without collap...
