| 20080221262 | Fluorinated POSS as alloying agents in nonfluorinated polymers - 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. In addition to mechanical properties, other physical properties are favorably improved, including lower thermal conductivity, dielectric properties, fire resistance, gas permeability and separation. These improved properties may be useful in a number of applications, including space-survivable materials and seals, gaskets, cosmetics, and personal care. | 09-11-2008 |

| 20090176006 | BIOMIMETIC MATERIALS COMPRISING POLYHEDRAL OLIGOMERIC SILSESQUIOXANES - Nanostructured chemicals such as polyhedral oligomeric silsesquioxanes, polyhedral oligomeric silicates, and polyhedral oligomeric metallasesquioxanes are attached to living and nonliving systems as biomaterials to provide a nanoscopic topology that favors biomimetic function and cellular modulation. The resulting surface is nanoscopically thin, nanoscopically dispersed, provides systematic chemistry, surface area, surface volume, surface topology, and is essentially free of impurities, and has controllable properties through selection of composition, R groups, nanostructure size and topology. Highly shape specific and chemically tailorable nanostructured molecules are sized to biological material dimensions and are compatible with all sterilization methods. | 07-09-2009 |
| 20100125123 | METALLIZED NANOSTRUCTURED CHEMICALS AS CURE PROMOTERS - Metallized polyhedral oligomeric silsesquioxanes and metallized polyhedral oligomeric silicates are used as cure promoters, catalysts, and 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 polymers, polyhedral oligomeric metallosesquioxanes (POMS) can be readily and selectively incorporated into polymers by common mixing processes. | 05-20-2010 |
| 20100137464 | POROSITY CONTROL WITH POLYHEDRAL OLIGOMERIC SILSESQUIOXANES - The use of nanostructured chemicals based on polyhedral oligomeric silsesquioxanes (POSS) and polyhedral oligomeric silicates (POS) are used to control porosity in organic and inorganic media. The precisely defined nanoscopic dimensions of this class of chemicals enables porosity to be both created (increased) or reduced (decreased) as desired. The thermal and chemical stability of the POSS/POS nanostructures and the ability of these nano-building blocks to be selectively placed or rationally assembled with both inorganic and organic material mediums allow tailoring of porosity. | 06-03-2010 |
| 20100305282 | METHOD FOR MODIFYING SURFACE PROPERTIES WITH NANOSTRUCTURED CHEMICALS - A method of using metallized and nonmetallized nanostructured chemicals as surface and volume modification agents within polymers and on the surfaces of nano and macroscopic particulates and fillers. Because of their 0.5 nm-3.0 nm size, nanostructured chemicals can be utilized to greatly increase surface area, improve compatibility, and promote lubricity between surfaces at a length scale not previously attainable. | 12-02-2010 |

Because of their tailorable compatibility with polymers, metals, composites, ceramics, glasses and biological materials, nanoscopic silicon containing agents can be readily and selectively incorporated into materials at the nanometer level by direct mixing processes. Properties improved include gas and liquid barrier, stain resistance, resistance to environmental degradation, radiation absorption, adhesion, printability, time dependent mechanical and thermal properties such as heat distortion, creep, compression set, shrinkage, modulus, hardness and abrasion resistance, electrical and thermal conductivity, and fire resistance.
