Colloidal Templating Fabrication of Aluminum‐Organophosphonate Films Using High Molecular Weight PS‐b‐PEO

High molecular weight polystyrene‐block‐poly(ethylene oxide) diblock copolymer (PS‐b‐PEO) is utilized as colloidal spheres in the presence of water. Adequately thick films with multilayers of spherical macropores are fabricated in one‐pot under highly concentrated conditions of PS‐b‐PEO. The frameworks are constructed using aluminum organophosphonate as a complicated hybrid component. The macropores (30–200 nm) are homogeneously distributed over the entire films and pore windows between the macropores are tunable (up to nearly 10 nm) by changing the relative amount of PS‐b‐PEO in the precursor solutions.
