Production of graphene by solution processing and development of graphene-based materials

Abstract:

Graphene produced by solution processing has attracted significant scientific and technological interest due to its applicability in a wide range of commercial applications from printing inks and coatings to structural composites. The requirements for these applications (high loading of conductive additive and tunable viscosity) have been a significant challenge in the graphene field. I will present the current graphene production methodologies and introduce an industrially scalable production route, namely microfluidization that can produce high quality defect-free graphene from graphite in large volumes in one step. I will then focus on different applications starting from graphene dispersions; the fabrication of conductive fibres using wet spinning, coatings using flexo/screen printing, and aerogels using freeze drying. I will finish my talk with my future plans at the University of Sunderland, on the development of new graphene-based materials (printing/stretchable inks, conductive adhesives and automotive composites).
