Abstract

Hybrid organic-inorganic membranes were prepared by size-exclusion deposition and thermal sintering of fluorescent polyphenylsilsesquioxane nanoparticles on a ceramic support. Fluorescent polyphenylsilsesquioxane particles were prepared by a two-step co-polymerization of phenyltriethoxysilane with 0.1 mol-% N-(triethoxysilylpropyl)dansylamide. Because they were larger than the pores in the support, the particles formed a layer on top of the ceramic support that was sintered at 300 °C into a homogeneous, non-porous membrane. Fluorescence of the modified polyphenylsilsesquioxane provided a valuable tool to monitor particle deposition and assist in characterization of the membranes.
