Abstract Process Process for incorporating carbon particles into a polyurethane surface layerThe invention relates to a method for introducing electrically conductive carbon particles into a surface layer comprising polyurethane. These carbon particles can in particular be carbon nanotubes. In the methodaccording to the invention, a solution of non-aggregated carbon particles having a mean particle diameter of 0.3 nm to ≤3000 nm acts in a solvent upon a surface layer comprising polyurethane. The solvent is able to cause the maceration of a surface layer comprising polyurethane. The dwell time is measured such that it is not sufficient to carry the polyurethane over into the solution. The invention furthermore relates to a polyurethane layer that comprises electrically conductive carbon particles and can be obtained by means of amethod according to the invention. The invention likewise relates to a polyurethane object having surface layer comprising electrically conductive carbon particles, obtainable by a method according to the invention.FIGURE 4
