TH12720B - Metallic film And capacitors containing such things - Google Patents

Abstract

suitable metal film to form capacitors metal film according to This invention consists of a polymer base film. and the vapor-bound layer with significant A1 and Zn fractions made on a polymer-based film, the amount of A1 in the vapor-bound layer is continually changing in its thickness direction, where quantity A1 corresponds to the equation a2 < a3 < a1, where a1 represents quantity A1 in percent thickness by weight relative to The total weight of A1 and Zn during duty lies between the vapor-bound layer. and such polymer base layer, a2 represents the volume A1 in the percentage sense by weight relative to the total weight of A1 and Zn centered in the direction of layer thickness. a3 represents the amount of A1 in the percentage sense. weight relative to the total weight of A1 and Zn in the surface of the vapor-bound layer.

Claims (9)

1. A metallized film composed of a polymer base film. and the floor that was captured on the island with vapors that dominate the A1 and Zn layers are made on such a polymer-based film in which the amount of AI in the vaporized layer is attached to it. continually changing in the direction of its thickness, where the quantity of AI corresponds to the equation a2 < a3 < a1 (where a1 represents the quantity A1 in the percentage-by-weight sense vs. The total weight of A1 and Zn during duty lies between the vaporized layer and the Based on the above polymer, a2 represents the quantity A1 in the percentage-by-weight sense relative to The total weight of A1 and Zn centered between the interfacial areas. and the surface area of the layer A3 is the amount of A1 in the percentage-by-weight sense. with the total weight of A1 and Zn in the surface of the vapor-bound layer. 2.
