We focus on liquid processing of these nanomaterials with the aim of developing nano-enabled applications. We have developed a novel method, liquid phase exfoliation, which can produce defect-free 2D nanosheets from a range of layered materials such as graphene, MoS2 and black phosphorous. An important part of this work involves the processing of liquid-suspended 2D nanosheets into functional structures using techniques such as spraying and inkjet printing. This allows the development of applications in areas such as printed electronic devices and energy storage. We also use or 2D nanosheets to develop nano-composites. These can be used in areas such as electromechanical sensing for health monitoring.
