摘要： The invention relates to a method for producing stretchable electrodes, where electrically conductive carbon particles, especially carbon nanotubes, are introduced into a coating comprising an elastomer. In said method, a preparation of non-aggregated carbon particles having an average particle diameter ranging from ≥ 0.3 nm to ≤ 3000 nm in a solvent acts upon a coating comprising an elastomer. The solvent can cause a coating comprising an elastomer to swell. The duration of the action is calculated so as to be insufficient to dissolve the elastomer. Optionally, another electrically conductive layer is applied. The invention also relates to a stretchable electrode obtained in said manner and to the use thereof.

摘要： The method for producing an electromechanical converter, comprises applying a monolayer of spacer elements (3) on a first polymer layer (1), where the spacer elements of the monolayer have generally the same height, applying a second polymer layer (2) on the spacer elements of the monolayer in such a way that a hollow chamber (4) is provided between the first polymer layer and the second polymer layer, and fixing the spacer elements between the first and second polymer layer. The spacer elements are formed in the form of ball and/or cord or rope. The method for producing an electromechanical converter, comprises applying a monolayer of spacer elements (3) on a first polymer layer (1), where the spacer elements of the monolayer have generally the same height, applying a second polymer layer (2) on the spacer elements of the monolayer in such a way that a hollow chamber (4) is provided between the first polymer layer and the second polymer layer, and fixing the spacer elements between the first and second polymer layer. The spacer elements are formed in the form of ball and/or cord or rope and are applied on the first polymer layer in meander-forming manner. The spacer elements are formed from glass or polymer and have a height of 1-800 mu m and/or a diameter of 1-800 mu m. The application of the spacer elements on the first polymer layer is carried out through printing process and/or coating process using printing- and/or coating materials, which comprise the spacer elements as filler. The fixing of the spacer element through partial hardening of the spacer element comprising printing- and/or coating materials is carried out after the application of the monolayer from the spacer element and completely mounting the spacer element is carried out after the application of the second polymer layer. The spacer elements are fixed though an adhesive process, where an adhesive layer is applied on the spacer element, first polymer layer and/or the second polymer layer through the application of printing- and/or coating materials through a printing- and/or coating process, and/or through a lamination process, where a thermoplastic layer is applied on the spacer element, first polymer layer and/or the second polymer layer through the application of the printing- and/or coating materials through a printing- and/or coating process, and/or the spacer elements and/or the first polymer layer and/or the second polymer layer are formed from a thermoplastic material, and/or through a clamping process, where the first polymer layer and the second polymer layer are clamped together through a clamp. The printing- and/or coating material comprises 1-component polyurethane and/or 2-component polyurethane, aqueous polyurethane dispersion and/or polyurethane-melt adhesive. The adhesive layer and/or the thermoplastic layer is a structured layer.
