Title: Doping graphitic materials: from fundamental interactions to scalable nanotechnology

Graphitic materials (fullerenes, carbon nanotubes, graphite and graphene) have extraordinary physical properties which imply huge industrial potential. However, despite a concerted global effort, important barriers to realising this potential remain. In this talk I will give examples from my recent research to describe how chemically doping graphitic materials can be used to:
1. Establish industrially scalable techniques for their separation and purification from as-produced heterogeneous mixtures, and for their scalable manipulation into films, composites and devices. [1, 2]
2. Tune their physical properties, in order to improve and extend their potential for applications and to search for exotic behaviour. [3,4]
