The manipulation and investigation of negatively charged 2D materials for applications

2-dimensional nanomaterials can have fascinating and technologically-relevant properties, high surfaces areas, and can be assembled into nanoscale devices, functional films and electrodes. It is anticipated that these materials will play an enormous role in the future industries of IT, healthcare and energy conversion and storage. We have recently discovered a new method for forming 2d nanosheets [1] and nanoribbons [2,3] in liquids with several unique characteristics: the nanomaterials are individually isolated and negatively charged permitting their controllable manipulation in unprecedented ways. In this project, we will develop methods for manipulating these nanomaterials into coatings, films and devices, by exploiting their charge for their scalable but high-precision manipulation by electro-deposition or depositing on chemical or charge patterned surfaces. We aim to produce and test real-world demonstrators from our deposited nanosheets with collaborators in UCL Chemical Engineering (corrosion resistant coatings/catalyst supports) and UCL Electrical Engineering (antennas).
