  • Patent number: 5529631
    Abstract: A length of sheet material is continuously surface treated, typically modified or coated, by continuously feeding helium gas or a helium gas mixture into a treating chamber while a plasma region is created in the gas under atmospheric pressure, continuously moving a length of sheet material into and out of the chamber through entrance and exit ports to pass through the plasma region, thereby continuously subjecting the sheet at either surface to plasma discharge treatment. The entrance and exit ports are sealed in a less gas tight manner to allow leakage of the helium gas or gas mixture.

  • Patent number: 5425832
    Abstract: Tightly integrated composite products are obtained by treating a fluoropolymer member on its surface with atmospheric pressure glow discharge plasma in a helium gas atmosphere containing 97% by volume or more of helium gas, and joining another member of rubber compositions, resins, metals, ceramics, or semiconductors to the surface treated fluoropolymer member. By using a fluoropolymer sheet as the fluoropolymer member and a metal or synthetic resin layer as the other member, there are obtained weather-resistant composite sheets in which the layer is firmly bonded to the fluoropolymer sheet.

  • Patent number: 5041304
    Abstract: Plates, sheets, fibers and other articles can be rendered water repellent by subjecting the articles at their surface to a glow discharge plasma under atmospheric pressure. The treating gas is a mixture of an inert gas and a fluorinated compound in the form of a cyclic or unsaturated hydrocarbon having some or all of the hydrogen atoms thereof replaced by halogen groups including fluorine atoms. The surface treatment lowers the surface energy of the articles in a long lasting manner.
