    • The present invention relates generally to hybrid organic-inorganic adsorbents for decontamination of fluids. Bridged poysilsesquioxanes are a family of hybrid organic-inorganic materials prepared by sol-gel processing of monomers that contain a variable organic bridging group and two or more trifunctional silyl groups. Specifically, the present invention relates to dipropylenedisulfide-co-phenylene-bridged polysilsesquioxane compositions, methods of making dipropylenedisulfide-co-phenylene-bridged polysilsesquioxanes, and methods of use of dipropylenedisulfide-co-phenylene-bridged polysilsesquioxanes. The present invention discloses properties of dipropylenedisulfide-co-phenylene-bridged polysilsesquioxanes that include high ligand loading, increased surface area, and increased porosity. These properties make dipropylenedisulfide-co-phenylene-bridged polysilsesquioxanes excellent adsorbents for decontamination of fluids for use in environmental and industrial processes.
    • 本发明一般涉及用于流体净化的混合有机 - 无机吸附剂。 桥联倍半硅氧烷是通过溶胶 - 凝胶加工含有可变有机桥连基团和两个或更多个三官能甲硅烷基的单体制备的杂化有机 - 无机材料族。 具体地说,本发明涉及二丙烯基二硫化物 - 共亚苯基桥连聚倍半硅氧烷组合物,制备二丙烯二硫化物 - 共亚苯基桥连聚倍半硅氧烷的方法,以及使用二丙烯二硫化物 - 共 - 亚苯基桥连聚倍半硅氧烷的方法。 本发明公开了二丙烯二硫化物 - 共亚苯基桥连聚倍半硅氧烷的性质,其包括高配体负载量,增加的表面积和增加的孔隙率。 这些性能使二丙烯二硫化物 - 共亚苯基桥连聚倍半硅氧烷在环境和工业过程中用于流体净化的优良吸附剂。
