  • Patent number: 10772218
    Abstract: A one-step react-on-demand (RoD) method for fabricating flexible circuits with ultra-low sheet resistance, enhanced safety and durability. With the special functionalized substrate, a real-time three-dimensional synthesize of silver plates in micro scale was triggered on-demand right beneath the tip in the water-swelled PVA coating, forming a three-dimensional metal-polymer (3DMP) hybrid structure of ˜7 ?m with one single stroke. The as-fabricated silver traces show an enhanced durability and ultralow sheet resistance down to 4 m?/sq which is by far the lowest sheet resistance reported in literatures achieved by direct writing. Meanwhile, PVA seal small particles inside the film, adding additional safety to this technology. Since neither nanomaterials nor a harsh fabrication environment are required, the proposed method remains low-cost, user friendly and accessible to end-users.

    Abstract: Disclosed is a method for providing an anti-corrosion protective coating to a metal substrate that uses a coating composition comprising a resin and a polyfunctional bridging molecule to both bind to the resin and to chelate the bound polymeric resin directly to the metal substrate. One category of polyfunctional bridging molecules preferably includes at least one amine function to bind to a resin and at least one carboxylate, thiol, silane, phenolate, acetoacetonate, imine, phosphate, or phosphonate function to chelate to a metal substrate. It is theorized that the amine function can bind to certain pendent chains in coating resins through a Michael addition reaction while the carboxylate, thiol, silane, phenolate, acetoacetonate, imine, phosphate, or phosphonate functions chelate to the metal substrate. These polyfunctional bridging molecules provide an organic binding of the resin to the metal substrates.

  • Patent number: 6929705
    Abstract: The present invention relates to metallic sheets having an improved antimicrobial property and also related to a method of manufacturing such sheets. More particularly, it relates to the continuous coating on metallic sheets with a resin composition containing antimicrobial additives. The surface of the metallic article is afforded antimicrobial properties by coating a liquid dispersion or solution of fine particles made of an antimicrobial ingredient on the surface of the metallic sheet dispersed in a uniform layer and cured or dried to affix to the metallic surface. The inorganic antibacterial particles are metal component-supporting oxides and zeolite powders. The inorganic antibacterial core particles have at least a primary surface coating of at least one metal or metal compound having antimicrobial properties. Roll coaters apply the coating.
