Precise Thermoplastic Processing of Graphene Oxide Layered Solid by Polymer Intercalation

Abstract The processing capability is vital for the wide applications of materials to forge structures as-demand. Graphene-based macroscopic materials have shown excellent mechanical and functional properties. However, different from usual polymers and metals, graphene solids exhibit limited deforma...
