    Abstract: Methods are provided for the fabrication of hydrophilic coatings on hydrophobic surfaces. In one embodiment, a polyethylene oxide (PEO) coating is fabricated on the surface of a polymeric material by contacting the surface with a methacrylic acid or acrylic acid monomer. The monomer first is reacted, for example by irradiation with an electron beam, to polymerize and covalently attach the monomer to the surface, to improve the hydrophilicity of the polymeric material. A coating of PEO molecules is subsequently attached to the polymer surface by hydrogen bond complexation. The PEO coating then may be covalently grafted onto the surface, for example, by irradiation grafting with an electron beam. The covalent grafting of a coating of the methacrylic or acrylic monomers to the surface greatly improves the wettability of the surface, and facilitates the covalent or non-covalent attachment of a coating of PEO to the polymer surface.

  • Publication number: 20030138573
    Abstract: A method of applying a polymer to a glass surface includes applying atmospheric plasma to a glass surface, applying a film of polymerizable fluid to the surface and curing the film with high-energy radiation. Apparatus for applying atmospheric plasma includes positive and ground electrodes, and an emitter strip of porous material with a plasma gas diffusing between the electrodes and through the emitter strip onto the glass surface.

  • Publication number: 20030087099
    Abstract: Methods are provided for the fabrication of hydrophilic coatings on hydrophobic surfaces. In one embodiment, a polyethylene oxide (PEO) coating is fabricated on the surface of a polymeric material by contacting the surface with a methacrylic acid or acrylic acid monomer. The monomer first is reacted, for example by irradiation with an electron beam, to polymerize and covalently attach the monomer to the surface, to improve the hydrophilicity of the polymeric material. A coating of PEO molecules is subsequently attached to the polymer surface by hydrogen bond complexation. The PEO coating then may be covalently grafted onto the surface, for example, by irradiation grafting with an electron beam. The covalent grafting of a coating of the methacrylic or acrylic monomers to the surface greatly improves the wettability of the surface, and facilitates the covalent or non-covalent attachment of a coating of PEO to the polymer surface.

  • Patent number: 6558732
    Abstract: A method for producing increased resistance to biodegradability is provided for biomedical devices subject to in vivo implantation. Among the steps required to produce such resistance are the application of a thermoplastic polyurethane coating to the device to provide a coating, and the subsequent crosslinking of the thermoplastic polyurethane coating through the application of radiation of a sufficient intensity and duration to convert said thermoplastic polyurethane coating to a thermoset coating possessing the attribute of increased biostability.

  • Publication number: 20030059544
    Abstract: The invention is directed to a photoresist-free method for depositing films composed of metals, such as copper or silica, or their oxides from metal complexes. More specifically, the method involves applying an amorphous film of a metal complex to a substrate. The metal complexes have a metal and a photo-degradable ligand. A preferred ligand is acac or alkyl-acac, expecially in combination with acetate ligands. These films, upon, for example, thermal, photochemical or electron beam irradiation may be converted to the metal or its oxides. By using either directed light or electron beams, this may lead to a patterned metal or metal oxide film in a single step. Low temperature baking may be used to remove residual organics from the deposited film. If silica is the metal, the deposited film has excellent smoothness and dielectric properties.

  • Patent number: 6528127
    Abstract: A printed packaging material and a method for making the same is described. On a primary surface of a thermoplastic flexible packaging material is disposed a printed image. That image includes two primary components. The first is at least one marking containing a pigment. The second is a pigment-free coating which overlies the outermost marking. The coating is made from materials which can polymerize and/or crosslink when exposed to ionizing radiation. After the film is exposed to such radiation, the coating hardens to form a protective layer over the printed markings.

  • Patent number: 6517343
    Abstract: A curable composition is placed on a candle, and then the composition is exposed to curing conditions such as ultraviolet light, to thereby cure the coating composition and provide a candle having a cured coating. The curable composition may be the reaction product of TMPTA (trimethylolpropanetriacrylate), itself the reaction product of trimethylolpropane and acrylic acid) and oleyl amine (an unsaturated primary amine having eighteen carbons). The candle may be made of wax or a gelled solvent, i.e., a mixture of gellant and solvent, particularly a hydrocarbon or other low polarity solvent. The undiluted coating may be applied by spraying on the oily surface of the candle. Ultraviolet cure of the coating occurs in 1-2 seconds.
