A newly developed process makes it possible to provide polymer surfaces being formed or modified in a moulding operation with electrical conductivity of up to 10<sup>-3</sup> S. Using a single simple process step, a highly-conductive network of carbon nanotubes is integrated within the outermost nanometre of the polymer surface. This new process, developed at the Fraunhofer IWS makes possible a wide range of novel applications such as plastics with antistatic or electrically-heatable surfaces or conductive plastic components for electrostatic painting and also lectron-optical components for solar cells, displays or lighting.
