摘要： A method and apparatus are taught for treating polyolefin containing or polyolefin-coated webs or laminates for obtaining the proper surface characteristics to promote adhesion of photosensitive coating materials and/or layers typically coated thereon. The web is passed through a high-voltage sheath region or dark space of the plasma generated by a powered electrode residing in a discharge zone. The frequency of the driving voltage must be above a lower bound dictated by the properties of the paper support and the plasma, and it must be below an upper bound beyond which the sheath voltages drop significantly and it is observed that the benefits of this approach diminish. The dark space is generated by a treatment electrode in a treatment zone. There is a counter electrode having a surface area in said treatment zone which is at least as great as the surface area of the treatment electrode. A power supply is included for driving the treatment electrode with an oscillating high voltage at a frequency less than about 2 MHz and greater than 1/tc where tc is the charging time of a web surface exposed to a rms ion current in the plasma.

摘要： Apparatus capable of sustained glow discharge at atmospheric pressure mounted along the web path in a web coating machine ahead of the point of coating application, for glow discharge treatment of the surface of a polymeric web shortly before coating. Latencies of treatment (the time between treatment and coating) approaching zero are possible, minimizing or preventing loss of treatment effect and maximizing adherence of a coated layer to the web surface. Elimination of one or more conventional subbing adhesion layers on the web surface is possible in some applications.

摘要： A medical implant has a microscopically rough outer coating that serves to bond the implant to animal tissue. The coating is applied to the implant by physical vapor deposition. The coating preferable is applied via a generally oblique coating flux or a low energy coating flux. In some embodiments, the coating has pores. The pores can contain a drug, which can diffuse over a period of time. The coating may be partially nonporous to protect the implant from corrosion. The coating can have an outer porous layer that can bond with animal tissue easily.

摘要： Apparatus for creating subatmospheric high plasma densities in the vicinity of a substrate in a work space for use in magnetron sputter deposition aided by ion bombardment of the substrate. Unbalanced flux lines emanating from cylindrical or frusto-conical targets cannot be captured across the work space, because the energizing magnets are cylindrical, and instead converge toward the axis of the apparatus to provide a high flux density, and therefore a high plasma density, in the vicinity of a substrate disposed in this region. The plasma profile and the coating material profile within the work space are both cylindrically symmetrical, resulting in a consistent and predictable coating on substrates.

摘要： Method and apparatus for making thermoplastic web from polyester or polyester blends for subsequent aqueous coating without requirement of an undercoat or primer coat for adhesion of subsequent coatings. Feedstock pellets of polymer, such as polyethylene terephthalate or polyethylene naphthalate, are melted in a screw extruder. Molten polymer is extruded from an extrusion die as a thick, high-viscosity ribbon, which is tempered and stretched in both the machine direction and the transverse direction to form a web of biaxially-oriented polymer of the desired width and thickness. The web is heated to a temperature above T.sub.g to set the biaxial orientation and then is glow discharge treated by passing it through an in-line glow discharge apparatus at atmospheric pressure wherein a stable glow discharge is produced in a gas mixture containing helium between two electrodes connected by an alternating power source operating at a voltage between 0.5 kV and 20 kV at a frequency between 60 Hz and 40 MHz. The web is coated with an aqueous gelatin subbing layer. The coated web then is maintained at elevated temperature. The combination of glow discharge treatment before sub coating and heat treatment after sub coating greatly enhances the adhesion of subsequently-coated aqueous gelatin layers such as photographic emulsions to the web, sufficiently that adhesion-promoting U-coat or primer coat as required in prior base-making methods can be omitted.
