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

二维纳米材料具有引人入胜和技术相关的特性，高表面积，可以组装成纳米级器件，功能薄膜和电极。预计这些材料将在未来的It、医疗保健、能源转换和存储等行业发挥巨大作用。我们最近发现了一种在液体中形成二维纳米片[1]和纳米带[2,3]的新方法，这些纳米材料具有几个独特的特性：它们是单独隔离的，带负电荷，允许它们以前所未有的方式进行可控操作。在这个项目中，我们将开发将这些纳米材料加工成涂层、薄膜和器件的方法，通过电沉积或沉积在化学或电荷图案表面上，利用它们的电荷进行可扩展但高精度的操作。我们的目标是与伦敦大学学院化学工程（耐腐蚀涂层/催化剂支撑）和伦敦大学学院电气工程（天线）的合作者一起，用我们沉积的纳米片生产和测试真实世界的样品。

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).
