Mesoporous Titanium Oxide‐Carbon Nanotubes Soot Films Dried under Gravity and Supergravity Conditions

The use of surfactant emulsions as templates to create highly porous titanium dioxide films deposited in stainless steel substrates is described. Polycondensations of sol‐gel titanium oxide occurs around emulsion droplets, which create voids in the final material. A second layer of carbon nanotubes soot dispersed in the surfactant creates a tandem system consisting of a reflector/porous/matrix/absorbing layer. The drying process for these films is performed in tilted and horizontal planes for two hours; one of the drying protocols was designed to be under terrestrial gravity conditions and in the other protocol, samples were dried on a centrifuge with 1.3 g and 7 g. In this work we compared the set of reflectance curves, SEM images and the thicknesses of the films just described.
