摘要:
Elastomeric components, such as a shoe outsole, are treated with a plasma application to clean and activate the elastomeric component. The application of plasma is controlled to achieve a sufficient surface composition change to enhance adhesion characteristics while not adversely physically deforming the elastomeric component. The plasma treatment is applied to increase carbonyl functional group concentrations within an altered region of the elastomeric component to within at least a range of 2%-15% of carbon atomic percentage composition. The cleaning and activation is controlled, in part, by ensuring a defined height offset range is maintained between the elastomeric component and the plasma source by a generated tool path. The elastomeric component may then be adhered, with an adhesive, to another component.

A primer layer comprising a polyvinyl butyral resin enhances adhesion of silver nanoparticle inks onto plastic substrates. The primer layer comprises a polyvinyl butyral (PVB) resin having a polyvinyl alcohol content between about 18 wt. % to about 21 wt. %. The PVB resin may also have a glass transition temperature greater than about 70° C. Optionally, the PVB primer layer may further be enhanced by cross-linking using a melamine-formaldehyde resin. Conductive traces formed on plastic substrates having the PVB primer layer exhibit an acceptable cross-hatch adhesion rating with little to no degradation of adhesion being observed after exposure to 4-days salt mist aging or 1-day high humidity aging.

The invention relates to a method for hydrophilizing surfaces of polymer workpieces. The method has a step (a) of pretreating the workpiece surfaces in a high-frequency gas plasma which is produced on the basis of an inert gas in order to clean and activate the workpiece surfaces; a step (b) of precoating the pretreated workpiece surfaces with polyacrylic acid using a high-frequency gas plasma made of a gas mixture, said gas mixture being composed of an inert gas and a first gas made of biocompatible, polymerizable carboxy group-containing monomers; and a step (c) of subsequently coating the precoated workpiece surfaces using a second gas substantially containing acrylic acid monomers.

A process for applying an overlayer to a cured thermoset molding composition is provided that includes exposing the cured thermoset molding composition to a plasma under conditions that modify the surface energy of a surface of the article without visually modifying the surface. The surface of the article is then overcoated with an overlayer having superior adhesion to a like article absent the intermediate plasma treatment. A component is also provided that is cured thermoset resin article having a shape and a surface. An overlayer is applied to the surface while the surface is still plasma activated. The overlayer is adhesion is unchanged by 4 weeks in a 100% humidity chamber at 30° C. over at least 95 area % of an interface between the overlayer and the surface.
