Mesoporous sandwiches: towards mesoporous multilayer films of crystalline metal oxides.
Alternating multilayers of ordered mesoporous films of different metal oxides were prepared with the EISA (evaporation-induced self-assembly) method, using block copolymer templates. Selecting certain metal oxides, as exemplified with TiO2 and WO3 in this work, a high mesoscopic order could be achieved and preserved during crystallization. In addition to standard characterizations, the electrochromism of the multilayer film was studied, proving good accessibility of the single layers.
