Abstract
A method is disclosed for fabricating laminations of mica and conductive foils for generation of ions in air. A layer of mica is laminated to sheets of metallic foil using pressure sensitive adhesive as the bonding material. The foil is etched in order to form electrodes in a desired pattern. The mica-foil laminate may include an encapsulating layer or tape of pressure sensitive adhesive around the edges.
Claims25
A method of fabricating a dielectric-electrode laminate comprising the steps of:
- (a) applying a layer of pressure sensitive adhesive to a sheet of mica, said pressure sensitive adhesive comprising a thermoplastic material selected from the class consisting of organopolysiloxane pressure sensitive adhesives,
- (b) bonding a face of a metallic sheet to a face of said mica sheet with said thermoplastic pressure sensitive adhesive, and
- (c) selectively removing portions of said metallic sheet to create an electrode pattern,
- wherein the dielectric-electrode laminate resists delamination due to moisture, and erosion due to ozone and nitric acid.

A dielectric-electrode laminate comprising:
- a mica sheet;
- at least one electrode bonded to a face of said mica sheet, said electrode being comprised of a metallic sheet, the bond between said electrode and said mica sheet being accomplished by a layer of thermoplastic pressure sensitive adhesive comprising an organopolysiloxane pressure sensitive adhesive,
- wherein the dielectric-electrode laminate resists delamination due to moisture, and erosion due to ozone and nitric acid.
A dielectric-electrode laminate comprising:
- a mica sheet having a thickness in the range from 2-75 microns;
- at least one electrode bonded to a face of said mica sheet, said electrode being comprised of a metallic sheet,
- the bond between said electrode and said mica sheet being accomplished by a layer of pressure sensitive adhesive selected from the class consisting of solutions of organopolysiloxane resins and acrylic-based pressure sensitive adhesives, said adhesive layer having a thickness in the range from 0.5 microns-5 microns,
- wherein the dielectric-electrode laminate resists delamination due to moisture, and erosion due to ozone and nitric acid.
