Frankland, “How Fillers Impact Extrusion Processing,” Plastics Technology (Nov. 2011), www.ptonline.com/columns/how-fillers-impact-extrusion-processing Graphene is a flat, single layer of carbon atoms in sheet form that is significantly stronger than steel.3 It has a high surface area-to-volume ratio, high tensile strength (how much it can stretch before it breaks), and high electron mobility (the speed at which its electrons move when voltage is applied).4 Graphene is not a new material, but it recently became commercially available and is now being used as a polymer additive.
