  • Production of graphene structures
    Publication number: 20210316992
    Abstract: According to an example aspect of the present invention, there is provided a method for producing graphene foam structures by assembling graphene or graphene oxide in a three-dimensional structure, wherein biomolecular surface active agents are used as a template in a water-based foam. The graphene foam structures produced by the method of the invention find industrial application for example in sensing and material applications.
