Abstract
A self-supporting sheet-like structure is described, which contains a substrate layer and a structured coating on at least one surface of the substrate layer. The structured coating is produced by treating at least one surface of the substrate layer by means of an electric corona discharge, which takes place between a high voltage electrode and a grounded counter-electrode. In this procedure, an aerosol containing discrete inert particles is simultaneously introduced into the corona discharge space during the corona discharge to improve the slip characteristics and reduce friction of the substrate layer.
