    Abstract: The present invention relates to a self-standing membrane made of metal oxide particles and polycarbonate. Said membrane combines the surface properties of porous colloidal metal oxide packings with the mechanical stability and flexibility of polycarbonate. The resulting porous film presents enhanced diffusion properties and, besides, the possibilityto design its optical response. The combination of metal oxide particles, of different and controlled size, and polycarbonate allows tailoring to measure the optical properties of the membrane in order to obtain from transparent to coloured or opaquefilms. On another side of this invention, the metal oxide particles of said hybrid membranes can be etched yielding an even more porous membrane. Furthermore, said porous films can be functionalised at different stages in the preparation wherebythe hybrid polycarbonate metal oxide film can be functionalised with active moieties, or the final polycarbonate film can be functionalised.
