摘要:
According to at least one aspect of the present invention, a method is provided for forming a polymerized coating on a surface of a substrate. In at least one embodiment, the method comprises providing a plasma gun having an outlet; introducing a pre-polymer molecule into the outlet of the plasma gun to form a number of fragments of the pre-polymer molecule as a plasma output including a direct-spray component and an over-spray component; at least partially isolating the direct-spray component and the over-spray component from each other to respectively obtain an isolated directed-spray component and an isolated over-spray component; and depositing at least a portion of the isolated direct-spray component and the isolated over-spray component onto the surface of the substrate through the outlet to form a base polymerized coating. The plasma gun is optionally operated at atmospheric pressure.

A structural polymer insert. The insert includes a substrate having a surface and an adhesive with the substrate being an admixture of a polypropylene component and a glass fiber component. The surface has a plurality of oxygen atoms, optionally introduced by air plasma, in an amount of 1 to 60 atomic percent of all the atoms present on the surface. The foam adhesive is attached to the surface through one or more reactive moieties resulted from oxidative action of the oxygen atoms.

A method is provided for decorating a plastic component having an exterior surface with an initial surface energy. At least a portion of the exterior surface is decorated with a coating. The method comprises fixturing the plastic component. At least the portion of the exterior surface is positioned substantially within a specified tolerance. Plasma treating at least the portion to a treated surface energy greater than the initial surface energy with an atmospheric-pressure air plasma nozzle. Applying the coating to at least the portion of the exterior surface, wherein the coating has a coating surface energy that does not substantially exceed the treated surface energy. The coating is then cured.

A surface treatment for polymeric part adhesion and a treated part is provided. In one aspect, a method for adhesively securing a part to a polymeric substrate is provided comprising providing an adhesive layer having a bonding surface having a first oxygen composition, a part having a bondable surface, and a polymeric substrate having a mating surface. Spray from an air plasma device is directed onto at least a portion of the bonding surface of the adhesive to provide a second oxygen composition on the bonding surface of the adhesive layer, with the second oxygen composition being greater than the first oxygen composition. The adhesive layer is secured between the bondable surface of the part and the mating surface of the polymeric substrate.
