Method of making a multilayer composite
First Claim
1. A method of providing a multilayer composite of layers of a dielectric film and an electrically conductive layer, the method comprising:
- forming a shape defining element through roll-to-roll embossing using an embossing drum having a corrugated microstructure about its circumference to providing the shape defining element with a surface pattern of raised and depressed surface portions corresponding to the corrugated microstructure of the embossing drum, the surface pattern having a periodically repeated sub-pattern several wavelengths long corresponding to the circumference of the embossing drum,providing a liquid polymer composition onto the surface pattern to form a first film of dielectric material having a front surface with a replicated surface pattern of raised and depressed surface portions and an opposite rear surface, the replicated surface pattern of raised and depressed surface portions including a periodically repeated sub-pattern several wavelengths long corresponding to the circumference of the embossing drum,depositing an electrically conductive layer onto the replicated surface pattern to form a first composite,providing a second composite comprising a film with a front surface and an opposite rear surface, the front surface comprising a surface pattern of raised and depressed surface portions,depositing an electrically conductive layer covering at least a portion of the surface pattern,arranging the first composite on the second composite, andfixating the position of the first composite relative to the second composite.

Abstract
A method for providing a multilayer composite includes the steps of providing a first composite comprising a film of a dielectric material with a front surface and an opposite rear surface, the front surface comprising a surface pattern; depositing an electrically conductive layer onto the surface pattern; providing a second composite comprising a film with a front surface and an opposite rear surface, the front surface comprising a surface pattern; depositing an electrically conductive layer covering at least a portion of the surface pattern; arranging the first composite on the second composite; and fixating the position of the first composite relative to the second composite.
