Abstract:
Exfoliation of graphene from graphite using multilayer coextrusion is generally disclosed. In some example embodiments, graphite may be dispersed within a first processing material, and the first processing material and a second processing material may be co-extruded through a plurality of series coupled layer multiplication dies to exfoliate graphene from the graphite. The graphene may be separated from the resulting multi-layered material. In some example embodiments, graphite flake and/or expanded graphite may be dispersed within the first processing material.
