Patent number: 7265194Abstract: This invention teaches the preparation and compositions of POSS nanostructured chemicals bearing a variety of onium-type surfactants. The surfactants serve as low-cost compatibilizing groups for polyhedral oligomeric silsesquioxane and polyhedral oligomeric silicate nanostructures with man-made polymer and biological systems. Variations of the surfactants also provide reactivity for the nanostructured chemicals with man-made and biological materials. The surfactant bearing nanostructured chemicals are useful as alloying agents is for controlling the structure and bulk physical properties of materials from the nanoscopic length scale.
