  • Patent number: 8857372
    Abstract: An isothermal, low pressure-based process of depositing material within a substrate has been developed and results in creating an extremely narrow reaction zone within which a more uniform and efficient deposition will occur. Sets of isothermal plasma operating conditions have been found that create a narrow deposition zone, assuring that the deposited material is clear glass rather than soot particles. The chemical delivery system, in one arrangement, utilizes rods of solid phase source material (which may otherwise be difficult to obtain in gaseous form). The operating conditions are selected such that the hot plasma does not transfer a substantial amount of heat to the substrate tube, where the presence of such heat has been found to result in vaporizing the reactant material (creating soot) and developing hot spots.

  • Patent number: 8642133
    Abstract: The present invention fabricates a hydrophobic and oleophobic polymer fabric through two stages of modification using atmospheric plasmas. The modified fabric has a rough surface and a fluorocarbon functional group having the lowest surface free energy. The fabric has a grafted fluorocarbon monomer layer to enhance the graft efficiency of the fluorocarbon functional groups and its wash fastness. The atmospheric plasmas can be mass produced and less expensively. Hence, the present invention can rapidly modify surfaces of polymeric materials with low cost and good environment protection.

  • Patent number: 8623466
    Abstract: Provided a method for producing an oriented-porosity dielectric material on a substrate. The method includes depositing a composite layer on a substrate by vapor deposition comprising a material forming a matrix and a compound comprising chemical groups capable of being oriented under the effect of an electromagnetic field and/or photonic radiation; treating the composite layer to obtain the cross-linking of the material forming a matrix; and subjecting the substrate coated with the composite layer to an electromagnetic field and a photonic radiation.

  • Publication number: 20130337185
    Abstract: A substrate has a surface printed with an ink or coating composition with excellent adhesion and dry rub resistance, and very good oil and saline rub resistance (crock) properties using a multi-functional carbodiimide as a crosslinker for nonwoven substrates. The rub performance of the ink or coating printed on a nonwoven substrate has been found to be superior to that of a first Sun benchmark ink including pigments for four color printing. In another embodiment, a carbodiimide crosslinker such as multifunctional Carbodilite SV-02 is added to the compositions to further improve rub resistance (crock) and retain liquid characteristics post inoculation when compared to compositions using aziridine as a crosslinker. In a further embodiment, a thin polyolefin film exemplifying a backsheet of a hygiene product was printed with the same crosslinked ink or coating composition and compared with a second Sun benchmark set of inks.

  • Patent number: 8597736
    Abstract: A method for producing polymer coatings by surface initiated polymerization from a plasma deposited coating is provided. The modification of surfaces by polymer attachment is a versatile and efficient means of controlling interfacial properties, such as surface energy (i.e. wetting behavior), permeability, bio-activity, and chemical reactivity. The present invention provides a method whereby a plasma deposited coating is applied to a substrate and the polymer coating formed by surface initiated polymerization is formed on the coating rather than the substrate itself. This means that the growth of the polymer using the grafting from procedure can be performed efficiently and independently of the substrate from.
