Abstract: The present invention relates to a coating system comprising a layer of carbon nanotubes aligned parallel to another, and a directly linked surface layer with metallic properties, from which said carbon nanotubes are grown in “tip” growth. The coating system may further comprise a base layer and/or a substrate. It can be obtained by producing a structured layer from a first phase, consisting of a metal having no independent catalytic activity in terms of the emergence of CNTs from the gas phase, and a second phase consisting of a metal, which catalyzes the emergence of CNTs from the gas phase, on a substrate or a base layer, wherein the first phase has an uneven thickness and/or folded structure potentially interspersed with pores, and the second phase is located in depressions and/or pores of the initial phase in such a way that both material phases are present at least partially next to each other in the lateral plane on said substrate or said base layer located thereon.
