Abstract

Flexible bicontinuous mesostructured polymer/inorganic composite membranes was prepared by undertaking co-assembly of surfactants and inorganic sol–gel processes inside pores of a preformed porous polymer membrane. After burning off the organic component, the oriented mesoporous TiO₂ film was obtained. The three dimensional porous structure was carefully investigated, and a DSSC was fabricated using the obtained TiO₂ film as photoanode. The method of incorporating surfactant induced self-organizing sol–gel process and a certain nanoporous template was proved to be a useful technique to create different kinds of nano-/mesoporous structures.
