Herein we describe the preparation of hybrid polymer-inorganic interfaces by the immobilization of polyoxometalate nanoclusters on functionalized polymer surfaces. The polymeric surfaces were made of polystyrene--poly(acrylic acid)/polystyrene (PS--PAA/PS) blends by spin coating on a silicon wafer. The functionalization of the polymer film was obtained by interfacial migration of the amphiphilic block copolymer toward the interface upon water vapor annealing. The carboxylic acid functional groups contained in the PAA block were then employed to anchor the [Ln(α-SiWO)] polyoxometalates (Ln: Ce, Er). This purpose was achieved by immersing the films in aqueous solutions of the in situ-formed inorganic nanoclusters. X-ray photoelectron and confocal Raman spectroscopies, together with atomic force microscopy, confirmed the immobilization of the inorganic species at the interface.
在此，我们描述了通过将多金属氧酸盐纳米团簇固定在功能化聚合物表面来制备聚合物-无机杂化界面的方法。聚合物表面由聚苯乙烯-聚（丙烯酸）/聚苯乙烯（PS-PAA/PS）共混物通过旋涂在硅片上制成。通过在水蒸气退火时两亲性嵌段共聚物向界面的界面迁移实现聚合物膜的功能化。然后利用PAA嵌段中含有的羧酸官能团来锚定[Ln(α-SiWO)]多金属氧酸盐（Ln：Ce、Er）。通过将薄膜浸入原位形成的无机纳米团簇的水溶液中来实现这一目的。X射线光电子能谱、共焦拉曼光谱以及原子力显微镜证实了无机物种在界面处的固定。
