    摘要: A method of using fluorinated-nanostructured POSS chemicals as alloying agents for the reinforcement of polymer microstructures, including polymer coils, domains, chains, and segments, at the molecular level. Because of their tailorable compatibility with nonfluorinated polymers, nanostructured chemicals can be readily and selectively incorporated into polymers by direct blending processes. The incorporation of a nanostructured chemical into a polymer favorably impacts a multitude of polymer physical properties. Properties most favorably improved are surface properties, such as lubricity, contact angle, water repellency, deicing, surface tension, and abrasion resistance. Improved surface properties may be useful for applications such as anti-icing surfaces, non-wetting surfaces, low friction surfaces, self cleaning. Other properties improved include time dependent mechanical and thermal properties such as heat distortion, creep, compression set, shrinkage, modulus, hardness and biological compatibility.

    摘要: A method of using olefin containing and silanol containing nanostructured chemicals as high temperature resins is described. Vinyl containing nanostructured chemicals are particularly effective in thermosets as they control the motions of polymer chains, and segments, at the molecular level. Silanol containing nanostructured chemicals are particularly effective in thermosets containing polar groups as the silanol can enhance polar group reactivity.. Nanostructured chemicals have tailorable compatibility with fluorinated polymers, and can be readily and selectively incorporated into polymers by direct blending and polymerization. The incorporation of a nanostructured chemical into a polymer improves polymer physical properties, particularly heat distortion and flammability characteristics, permeability, optical properties, texture, feel and durability, lower thermal conductivity, and gas oxygen permeability, in addition to time dependent mechanical and thermal properties such as creep, compression set, shrinkage, modulus, and hardness. These improved properties may be useful in applications including composite materials, foams, cosmetics, and durable coatings.
