Abstract: A material can have a layered structure with at least a first layer, including a carbon-based material or a substrate of a material other than a carbon-based material, a second layer, including a carbon-based material, and a third, intermediate layer that separates and interconnects the first and second layers. The carbon-based material includes at least 50 at. % carbon, has a hexagonal lattice and the layer or layers including the carbon-based material has/have a thickness of 1-20 times the size of a carbon atom. The intermediate layer is a layer that includes a salt having ions that include at least two separate cyclic, planar groups that are capable of forming ?-?-stacking with the material of the second layer and that the third, intermediate layer is connected to at least the second layer by ?-?-stacking caused by said cyclic planar groups of the salt ions.

Abstract: The present invention relates to graphene coated iron based particles and a method of producing such. Provided is a composite powder suitable for powder metallurgy and additive manufacturing processes comprising particles of an iron based material with a coating of a graphene based material wherein the concentration of the graphene based material is between 0.1 wt % and 1.0 wt %.

Abstract: A metal-graphene composite product in the form of a sliding contact of an electric power application, in which graphene flakes are dispersed in a matrix of the metal, as well as to a method for obtaining such a composite product.
