The plant world has over two hundred species that have the ability to clean themselves using rain water. They do so by having a highly structured surface that is composed of microscopic nodules. These nodules cause rain impacting on the surface to form almost completely spherical balls. These water balls roll across the surface and attract dust and debris from the plant surface- and enable the plant to clean itself. The aim of this project is to produce surfaces that mimic the action of these plants- we will make these hydrophobic surfaces by chemical vapour deposition. The chemical vapour deposition technique allows thin films of material to be laid down- the key feature is that the films are extremely well bonded to the underlaying surface. By controlling the surface structure- that is to make surfaces with a microscopic nodular apperance we will be able to make the surfaces very hydrophobic. Further we will investigate the effect of surface chemistry on these surfaces by adding specific elements that in themselves are water repelling. The applications of this work are enormous- if a surface can be made very hydrophobic not only will it self clean, it will also not mist. This means that it can be used on spectacles, bathroom mirrors and the indside of cars to stop them fogging up. It could also be used on the exterior surface of a window pain to keep the window clean and bright.

植物世界拥有超过200种的物种，可以使用雨水清洁自己。他们通过具有由微观结节组成的高度结构的表面来做到这一点。这些结节会导致雨水影响表面几乎完全球形球。这些水球沿着表面滚动，吸引植物表面的灰尘和碎屑，并使植物能够清洁自身。该项目的目的是产生模仿这些植物作用的表面 - 我们将通过化学蒸气沉积使这些疏水表面。化学蒸气沉积技术允许放置材料的薄膜 - 关键特征是这些薄膜非常粘合到底层表面。通过控制表面结构，即用微观结节表面使表面使表面变得非常疏水。此外，我们将通过添加本身是排出水的特定元素来研究表面化学对这些表面的影响。这项工作的应用是巨大的 - 如果可以使表面变得非常疏水，它不仅会自我清洁，也不会雾化。这意味着它可以在眼镜，浴室镜子和汽车的独立面上使用，以阻止它们雾化。它也可以在窗户疼痛的外表面上使用，以保持窗户清洁明亮。
