Abstract

The present invention relates to a method for coating substrates with a carbon-based material, comprising the steps of at least partially coating a substrate with a polymer film on at least one outside surface of the substrate and carbonizing the polymer film in an atmosphere that is essentially free of oxygen at temperatures in the range of 200° C. to 2500° C.
