Abstract (en)
[origin: EP2284933A1] The method for producing stretchable electrodes with a surface layer (1, 2) containing electrically conductive carbon particles, comprises contacting surface layer of an elastomer with preparation of non-aggregated carbon particles, where the elastomer is provided with glass transition temperature (T g) of -130[deg] C to 0 [deg] C and the preparation of carbon particles has an average particle diameter of 0.3-3000 nm in a solvent, which causes swelling of the surface layer of the elastomer, and impinging the preparation of the carbon particles on the surface layer of the elastomer for a time period. The method for producing stretchable electrodes with a surface layer (1, 2) containing electrically conductive carbon particles, comprises contacting surface layer of an elastomer with a preparation of non-aggregated carbon particles, where the elastomer is provided with a glass transition temperature (T g) of -130[deg] C to 0 [deg] C and the preparation of the carbon particles has an average particle diameter of 0.3-3000 nm in a solvent, which causes a swelling of the surface layer of the elastomer, impinging the preparation of the carbon particles on the surface layer of the elastomer for a time period, which is insufficient to dissolve the elastomer in the solution, ending the impingement of the preparation of the carbon particles on the surface layer of the elastomer, and applying an additional electrically conducting layer (4, 5) on the surface layer, where the obtained electrically conducting layer breaks or tears during stretching the surface layer. The impingement of the preparation of the carbon particles on the surface layer of the elastomer occurs under the use of ultrasound and/or heat. The carbon particles are carbon nanotubes, single-walled carbon nanotubes, multi-walled carbon nanotubes, carbon nanohorns, carbon nano-onions, fullerene, graphite, graphene, carbon fibers, carbon black and/or carbon black. The surface layer of the elastomer is covered by a mask. An independent claim is included for a stretchable electrode.
