    摘要： Fluoroalkylsilane-treated metal oxide particles and a fluoroelastomeric binder are dispersed in a fluorinated solvent with a low boiling point and applied to a substrate via spray deposition. The spray deposition process rapidly produces a conformal coating that features low surface energy and surface topography with a large range of characteristic length scales and re-entrant curvature, thereby imparting superoleophobicity. The degree of superoleophobicity is readily adjusted by means of altering the ratio of particles to binder. The choice of particle and binder result in coatings with thermal stability for thousands of hours at temperatures up to 200 degrees Celsius as well as desirable mechanical characteristics.

    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. 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.

    摘要： A method of using nanostructured chemicals as alloying agents for the reinforcement of flouropolymer microstructures, including polymer coils, domains, chains, and segments, at the molecular level. Because of their tailorable compatibility with fluorinated polymers, nanostructured chemicals can be readily and selectively incorporated into polymers by direct blending processes. Properties most favorably improved are time dependent mechanical and thermal properties such as heat distortion, creep, compression set, shrinkage, modulus, hardness and abrasion resistance. In addition to mechanical properties, other physical properties are favorably improved, including lower thermal conductivity, fire resistance, and improved oxygen permeability. These improved properties may be useful in a number of applications, including space-survivable materials and creep resistant seals and gaskets. Improved surface properties may be useful for applications such as anti-icing or non-wetting surfaces or as low friction surfaces.

    摘要： Method for enhancing the crystallization rates of engineering thermoplastics through the use and incorporation of particulate additives with dimensions on the order of 10-1000 nm is described. The presence of nanoparticles at concentrations of, e.g., less than 10 weight percent of the composition, reduces the viscosity of the thermoplastics as compared to the respective homopolymer, thereby increasing polymer chain transport and diffusion to the crystallizing growth front. The prescription of this technology has been shown to reduce crystallization half times of some engineering thermoplastics by as much as 40 percent at optimal crystallization temperatures, an effect that is magnified as the temperature is reduced towards the glassy state of the amorphous phase. Nano-modified engineering thermoplastics with rapid crystallization kinetics and relatively low viscosities can be utilized in component fabrication processes that require rapid processing times, e.g., for the sake of cost efficiency.

    摘要： Coated particles comprise a core of fumed or precipitated inorganic metal oxide having a surface area of about 50 to about 500 square meters per gram and a shell consisting of an array of fluoroalkyl molecular chains at a density of at least 1 chain per square nanometer, joined to the core by covalent chemical bonds and with a total organic content of at least 9.9 percent by weight. These particles are formed by the chemical attachment of fluoroalkyl-alkylsilanes after exposure to an alkylamine and followed by an extraction to remove any organic material not covalently bound. The dense packing of molecular chains in the fluoroalkyl shell combined with a mesoporous structure imparts a very low surface energy, a very high specific surface area, and surface texture over a wide range of length scales. Such features are highly desirable for the creation of, for example, superhydrophobic and superoleophobic surfaces, separation media, and release films.
