  • Patent number: 8021723
    Abstract: A method for processing a substrate by plasma CVD includes: (i) forming a film on a substrate placed on a susceptor by applying RF power between the susceptor and a shower plate in the presence of a film-forming gas in a reactor; and (ii) upon completion of step (i), without unloading the substrate, applying amplitude-modulated RF power between the susceptor and the shower plate in the absence of a film-forming gas but in the presence of a non-film-forming gas to reduce a floating potential of the substrate.

  • Patent number: 6537932
    Abstract: A method of preparing a sterilized nonwoven web, which method includes providing a nonwoven web; coating the nonwoven web with from about 0.005 to about 3 percent by weight, based on the weight of the web, of an antistatic agent; and exposing the coated nonwoven web to an oxidizing gas plasma. The antistatic agent is adapted to be free of a malodor after exposure of the coated nonwoven web to the oxidizing gas plasma. The antistatic agent may be further adapted to provide a sterilized nonwoven web having a hydrohead value as measured by Method 5514 of Federal Test Method Standard No. 191A which is at least 50 percent of the hydrohead value of the coated nonwoven web before exposure to the oxidizing gas plasma. The antistatic agent also may be adapted to provide a sterilized nonwoven web having a surface resistivity in ohms which is lower than the surface resistivity in ohms of the coated nonwoven web before exposure of the coated nonwoven web to the oxidizing gas plasma.

  • Patent number: 6432189
    Abstract: An antistatic composition for treating a substrate such as paper for use in a photocopier or the like, in rolls, or bundles in which sheets of the substrate are individually fed from a bundle of sheets of the substrate, comprises a single phase hydrocarbon oil composition. The hydrocarbon oil may optionally include additional antistatic additives. The composition reduces static between the individual sheets in the bundle, thus reducing paper misfeeds and jams when individual sheets in the bundle are fed into the photocopier. Also disclosed is a method of treating a substrate for use in a photocopier in which sheets of the substrate are individually fed from a bundle of sheets of the substrate, or rolls of a substrate, with an antistatic composition to reduce static between the individual sheets of the substrate. The method includes applying an antistatic composition including a hydrocarbon oil to at least one lateral margin of the bundle of sheets of the substrate.
