A process for producing an electrical conductor structure that involves embedding at least one metallic conductor track and at least one heating conductor in an electrically insulating substrate, and producing an electric current in the heating conductor so that a first layer of the substrate and a second layer of the substrate fuse in an area surrounding the heating conductor, to seal an interface between the two layers.

The present method includes graphene, preferably in the form of flat graphene oxide flakes with, by mass, preferably between 0.5% and 35% PAN. The graphene oxide and conductive-polymer PAN is in a co-suspension in water and is co-deposited on a surface. The deposited PAN with a high-percentage graphene-oxide layer is dried. Our tests have produced electrical conductivities 1000 times more conductive than the PAN by itself. Our testing indicates that using flakes that are flat is essential to getting very high conductivity, and that controlled oxidation is very important in suspending graphene oxide in water.
