Methods and systems utilize an atmospheric-pressure nitrogen dielectric-barrier discharge to treat the surface of polymer substances. The atmospheric-pressure nitrogen dielectric-discharge may be maintained with a level of H2O below a pre-defined amount, such as by measuring and controlling the H2O within a treater, to produce a surface treatment for a polymer substance that yields desirable characteristics. Furthermore, the H H2O level may be measured and controlled according to a pre-defined amount or according to another parameter such as an analysis of the resulting polymer surface. For example, the polymer surface may be provided with an optimal added nitrogen-to-added oxygen ratio and/or an optimal stability based on washed and unwashed advancing contact angles such as by controlling the H2O level within the treater based on these analyses of the treated polymer.

Methods of bonding polyester substrates together, comprising externally delivering thermal energy onto the bonding surfaces of the substrates and bringing the bonding surfaces into proximity with each other and bonding the substrates to each other.
摘要:
The present invention provides a method of modifying the surface of a polymeric substrate, e.g., to improve the wettability of the polymer film surface and/or alter the metal adhesion properties of the surface of the substrate by exposing the substrate to a flame. The flame is supported by an oxidizer and fuel mixture that includes an effective amount, for modifying the polymeric substrate, of at least one sulfur-containing compound that functions as a fuel substitute. In addition, substrates are provided that have increased wettability or increased metal adhesion performance.

A polymeric film having a plurality of perforations, which are specially structured and arranged is described. The polymeric film provides a strong, high-tensile strength material that permits hand tearing of the film along a desired tear path, providing a controlled tear propagation line. The polymeric film may also be incorporated into a multi-layer film having cloth-like properties of strength and tear propagation, and is suitable for use various adhesive tape applications. Methods of making the polymeric film are also disclosed.
摘要:
An aperture mask is provided comprising an elongated web of flexible film having at least one deposition mask pattern formed in the film, wherein the deposition mask pattern defines deposition apertures that extend through the film that define at least a portion of one or more electronic circuit elements, and wherein deposition apertures are bounded by a rim, the rim being a portion of the mask which has a thickness greater than an average thickness for the mask. In another aspect, the present invention provides a method of making such an aperture mask comprising the steps of: providing a support surface, wherein the support surface includes a plurality of lowered portions; providing a burner, wherein the burner supports a flame, and wherein the flame includes a flame tip opposite the burner; contacting at least a portion of an elongated web of flexible film against the support surface; and heating the film with a flame from a burner to create apertures in the film in the areas covering the plurality of lowered portions.

A coating composition is disclosed. The coating composition includes a poly(methyl methacrylate) polymer or copolymer having a weight average molecular weight of at least 50,000 grams per mole; monomer comprising at least one of an alkylene diacrylate, alkylene dimethacrylate, cycloalkylene diacrylate, or cycloalkylenedimethacrylate, wherein the at least one of an alkylene diacrylate, alkylene dimethacrylate, cycloalkylene diacrylate, or cycloalkylenedimethacrylate provides at least 80 percent by weight of the monomer; and a stabilizer against ultraviolet light. An article including a coating on a surface of a substrate and a method of making the article are also disclosed. The coating on the surface of the substrate is obtained by curing the disclosed coating composition.
