Graphene, a nanocarbon with exceptional physical and electronic properties, has the potential to be utilised in a myriad of applications and devices.  To realise this, the development of scalable chemistries is required that facilitates processing and fabrication in such a way that the inherent properties of graphene are maintained within the material structures or devices. This will involve chemistries for the most part that enable efficient graphene integration with a host polymer, and that result in formulations with rheological properties that allow the use of fabrication tools such as fibre spinning or printing.1


We have developed chemical exfoliation methods of both graphene oxide and graphene itself that afford processable dispersions in both aqueous and organic solvents and explored their use for the preparation of a variety of material composites, materials useful for the fabrication of graphene-containing structures and devices.2,3,4,5


In this lecture, we will discuss the preparation and application of these processable graphene dispersions, and the relative merits of each approach to the development of graphene composites and devices.

David Officer is Professor of Organic Chemistry in the Intelligent Polymer Research Institute and the ARC Centre of Excellence for Electromaterials Science (ACES) at the University of Wollongong. He obtained his PhD in Chemistry at Victoria University of Wellington, Wellington, New Zealand in 1982 and joined the lecturing staff at Massey University in 1986 after three years research work in organic chemistry at the Australian National University and as an Alexander von Humboldt Fellow at the University of Cologne, Cologne, Germany. During his 21 years at Massey University, he became founding Director of the Nanomaterials Research Centre and Professor in Chemistry in the Institute of Fundamental Sciences at Massey University, New Zealand. David joined ACES in 2007 and leads the Electromaterials research theme in ACES, developing new materials such asspiropyrans, porphyrins, polythiophenes, graphene and graphene/polymer composites. He is also responsible for organic materials synthesis, including graphene synthesis, in the Materials Node of the Australian National Fabrication Facility and leads the Polymers for Solar Cells Program in the Australian Cooperative Research Centre for Polymers.David has published more than 190 papers in the areas of photoactive materials, conducting polymers, nanomaterials, nanostructured carbons, polymer composites and solar cells. In 2004, he was awarded the New Zealand Institute of Chemistry HortResearch Prize for Excellence in the Chemical Sciences.
