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.
高分子量聚苯乙烯嵌段聚氧化乙烯两嵌段共聚物（PS-b-PEO）在水中用作胶体球。在 PS-b-PEO 的高浓度条件下，一锅法制备具有多层大孔球形的足够厚的薄膜。该框架使用铝有机磷酸酯作为复杂的杂化组分构建。大孔（30-200nm）在整个薄膜上均匀分布，并且通过改变前体溶液中 PS-b-PEO 的相对量，可以调节大孔之间的孔窗（高达近 10nm）。
