  • GRAPHENE OXIDE-BASED POROUS 3D MESH
    Publication number: 20210214678
    Abstract: A method of making a porous three-dimensional graphene mesh includes combining a graphene-containing material and a polymer having a plurality of hydroxyl groups in an alcohol solvent to form a mixture, adding a salt to the mixture, heating the mixture to form a gel, and washing the gel with water to remove the salt from the gel, leaving behind stable pores to form a scaffold. A three-dimensional porous graphene mesh includes a graphene-containing material and a polymer. The polymer is crosslinked with the graphene-containing material such that the Young's Modulus of the mesh is at least about 5 GPa.
    Type: Application
