  • 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.

  • Publication number: 20140106141
    Abstract: One or more aspects of the disclosure pertain to an article including a film disposed on a glass substrate, which may be strengthened, where the interface between the film and the glass substrate is modified, such that the article has an improved average flexural strength, and the film retains key functional properties for its application. Some key functional properties of the film include optical, electrical and/or mechanical properties. In one or more embodiments, interface exhibits the effective adhesion energy is about less than about 4 J/m2. In some embodiments, the interface is modified by the inclusion of a crack mitigating layer between the glass substrate and the film.

  • Publication number: 20140072741
    Abstract: The present invention is directed to a method of treating a reinforcement cord, comprising the steps of A) atomizing a mixture of at least one polymerizable monomer, a halogenated saturated hydrocarbon, and a carrier gas to form an atomized mixture; B) generating an atmospheric pressure plasma from the atomized mixture; and C) exposing the reinforcement cord to the atmospheric pressure plasma under conditions suitable to form a polymer strongly bonded to the tire cord and capable of bonding to rubber.

  • 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.
