    Abstract: Variations of this invention provide durable, impact-resistant structural coatings that have both dewetting and anti-icing properties. The coatings in some embodiments possess a self-similar structure that combines a low-cost matrix with two feature sizes that are tuned to affect the wetting of water and freezing of water on the surface. Dewetting and anti-icing performance is simultaneously achieved in a structural coating comprising multiple layers, wherein each layer includes (a) a continuous matrix; (b) discrete templates dispersed that promote surface roughness to inhibit wetting of water; and (c) nanoparticles that inhibit heterogeneous nucleation of water. These structural coatings utilize low-cost, lightweight, and environmentally benign materials that can be rapidly sprayed over large areas using convenient coating processes.

  • Patent number: 7790265
    Abstract: A surface energy gradient on a fluid-impervious surface and method of its creation comprising the steps of a) Exposing a base surface having a proximal and a distal portion to a first solution comprising at least one molecule of the formula X-J-M1 wherein X and M1 represent separate functional groups and J represents a spacer moiety that, together, are able to promote formation from solution of a self-assembled monolayer for sufficient time to form a monolayer surface having a uniform surface energy on the base surface. b) Removing a portion of the monolayer of (a) such that a portion of the base surface is again fully or partially exposed. (c) Exposing the portion of the base surface from (b) to at least one other molecule including a functional group having a different surface energy from that of the functional group removed in(b) such that a surface energy gradient from a proximal location to a distal location is formed.

  • Patent number: 7763110
    Abstract: A method of predicting photostability of coatings with various dopants on titanium dioxide pigment particles is disclosed. Calculations of the density of states show that a doped coating which reduces the density of states near the band edge or increases the density of states within the band gap of the pigment particles increases the photostability of the doped pigment.

  • Patent number: 7718219
    Abstract: A method for forming channels within a dried chromonic layer is described. A coating composition is applied to a substrate, dried, and exposed to a hydrophilic organic solvent forming a channel pattern having a first set of channels, and a second set of channels that are substantially perpendicular to the first set of channels. A deposition material may be disposed within the channels to form a nanostructured pattern. An article having a channel pattern is further described.

  • Patent number: 7582343
    Abstract: A surface-modified article is formed of an elastomeric matrix, such as a glove shape, and a plurality of fine silica particles affixed to at least a portion of the surface of the matrix, the outside surface in the case of the glove. The fine silica particles increase the coefficient of friction of the article surface. The fine silica particles may also be made electrically conductive, so that static charge at the surface of the article is dissipated. The silica particles are applied by mixing them into a coating composition, applying the coating composition to the surface of a mold, and solidifying a flowable elastomeric composition against the coated surface. The coating composition may include a coagulant or a parting agent.

  • Publication number: 20090162609
    Abstract: A sizing composition for reinforcement fibers that includes a cationic modified polyurethane dispersion, one or more silane coupling agents, and at least one lubricant is provided. The cationic modified polyurethane dispersion includes a dual end-capped polyurethane selected from a silane-terminated polyurethane, a ketoxime-terminated polyurethane, or a hybrid silane/ketoxime-terminated polyurethane where one end of the polyurethane is terminated with a silane group and the opposing end is terminated with a ketoxime group. The size composition is applied to reinforcement fibers and formed into chopped strand, wet-laid mats that can be used for a variety of purposes, including roofing products. Chopped strand mats formed from fibers sized with the inventive sizing composition maintains or improves the dry tear strengths and wet strengths compared to chopped strand mats made from fibers sized with a commercial sizing composition that does not contain a modified cationic polyurethane dispersion (e.g., SPUD).
