Poly(methacrylic acid)/CdS(PMAA /CdS)spherical organic-inorganic composites with core-shell structures were prepared by utilizing polymeric microgel template effe ct on inorganic precipitation. The c om-posites were produced via two steps.

• 以微凝胶为模板；利用微凝胶三维网络结构对无机沉积反应的限域和导向作用；制备了具有核-壳结构的聚甲基丙烯酸/硫化镉(PMAA/CdS)有机/无机复合微球材料.
