A versatile colloidal templating strategy to fabricate hierarchically structured inverse opals is investigated. A sequence of infiltration and pyrolysis steps provides access to a range of material combinations such as SiO 2 , Al 2 O 3 , or TiO 2 . The experimental results also document the feasibility of this method to fabricate porous polymer films with a double periodic pore lattice.
