Polysilsesquioxanes were prepared in spherical shape with diameters from a few hundred nanometers to micrometers. The spheres containging vinyl, mercapto, and amine groups were exposed to aqueous solutions of silver, gold, platinum, palladium ions. Many of polysilsesquioxane spheres reduced these metal ions to form nano sized matal particles and fixed the metal nanoparticles within them. The maximum amounts of metal ions reduced by polysilsesquioxane spheres were dependent on the composition of polysilsesquioxanes. Also, the size of metal nanoparticles, and the locaton of formation were dependent on the composition of polysilsesquioxanes. In this poster, the capacity of polysilsesquioxanes reducing metal ions, the morphology of composites of metal nanoparticles and polysilsesquioxane spheres will be presented. |
