  • Patent number: 11518828
    Abstract: The present invention relates to processes for making macromolecular networks, macromolecular networks made by such processes, and methods of using such macromolecular networks. Such process employs a low amount of amine compound as a reaction accelerant. The rates of chemical reaction are thereby easily controlled over several orders of magnitude, permitting efficient catalysis and control of reaction conditions needed to produce thermochemically stable macromolecular networks.

  • Patent number: 8853343
    Abstract: A process and thermoset resin structures having: number of —OCNs attached to phenyl rings exceeds number of phenyl rings (provides glass transition temperature of 334° C. when combined with flexible bridge); bridge between rings does not hinder rotation and allows maximum rotational degrees of freedom (allows complete cure at temperatures less than 350° C.); and bridge between rings is small enough to maintain cyanurate density and allows for high char yields.

  • Patent number: 8741432
    Abstract: 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.

  • Patent number: 8580027
    Abstract: 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.
