  • Publication number: 20200248008
    Abstract: An anti-fouling coating comprising a polymeric compound, wherein a backbone of the polymeric compound is covalently bonded to a quorum sensing inhibitor, and wherein the anti-fouling coating has substantially no bactericidal activity, the quorum sensing inhibitor is substantially non-leaching from the anti-fouling coating, or both.

  • Patent number: 10570230
    Abstract: The invention relates to a heterogeneous, co-continuous copolymer composition of vinylidene fluoride and at least one other comonomer. Preferred comonomers are hexafluoropropylene and perfluoroalkylvinyl ether. The co-continuous morphology is provide by first forming a first phase polymer, then adding one or more comonomers before half of the original monomer stream has been added, and at an effective level to cause phase separation of the copolymer. The co-continuous morphology provides a means for incorporating a high level of comonomer into the copolymer with little or no adverse effect on the melting temperature. The morphology also provides the copolymer composition with a unique combination of properties, including a high melting point, good flexibility and good low temperature impact resistance. The unique properties of the polymer make it useful in end-use application where those properties provide performance advantages, such as in the wire and cable market, and in oil and gas applications.

  • Publication number: 20190379040
    Abstract: Electrodes including a passivation layer formed prior to receiving an initial charge are provided. The electrodes comprise an electrode-composition including an active electrode species, in which the electrode-composition comprises a first surface. The electrodes also comprise a passivation layer positioned directly or indirectly onto at least a portion of the first surface. The passivation layer comprises a polymeric material and at least a first electrolyte. The electrodes can be included into an aqueous electrochemical cell. Methods of forming an electrode in the form of a thin layer or film are also provided. Methods of forming an aqueous electrochemical cell are also provided.

  • Publication number: 20190352517
    Abstract: A surface treatment formulation configured to inhibit scaling or climbing of a surface is provided. The surface treatment formulation may include a base binding material configured to adhere to the surface and a filler material embedded in the base binding material. The filler material may include a dry lubricant having a layered lamellar structure or low inter filler interaction. Furthermore, the surface treatment formulation may be configured to be activated in order to expose the filler material thereby causing formation of a slippery surface to inhibit the scaling or climbing of the surface.

  • Patent number: 9115493
    Abstract: The present invention provides aqueous coating compositions comprising one or more emulsion copolymer made from itaconic acid, a sulfonic acid or sulfonate ester monomer and an additional acid monomer which is a carboxylic acid and having a glass transition temperature of from ?45° C. to ?10° C., and one or more pigment, opacifier, filler, extender, or mixture of any of these at a % PVC of from 20 to 55, preferably 30 to 50, wherein coatings made from the coating compositions provide improved resistance to water swelling and dirt pickup resistance. The improvements are observed regardless of whether the compositions contain or are substantially free of zinc or divalent metal ions, or salts or compounds containing them. The present invention also provides roofing substrates coated with the aqueous compositions.
