减反射膜是一类量大面广、在光学材料与器件领域具有重要应用的薄膜材料。目前，对于菲涅尔透镜等具有微结构的光学材料，在其表面构筑结构均匀的纳米减反射膜的研究鲜有报道。本项目以在微结构光学表面构筑共形、厚度均匀可控的多功能减反射膜为目标，重点研究成膜新方法，探索成膜物质在微结构表面的均匀成形的机理、控制薄膜厚度及结构形态的关键因素；进一步地，赋予上述减反射膜其他功能，如防涂鸦、防指纹、自清洁、高强度等；研究薄膜的防污效果、薄膜结构与防污性能和机械强度之间的关系，拟解决功能性减反射膜制备过程复杂、成本高、不便于大规模制备等问题。通过本项目研究，期望为具有微结构光学材料或器件表面的减反射提供一种简便、易于大面积应用的新方法，为推广其应用奠定技术基础。

Antireflective coatings are of great importance and widely used in the field of optical materials and devices. At present, there are few reports on the fabrication of uniform nano-antireflective coatings on the micro-structured surfaces of optical materials such as Finel lens. This project intends to develop the new methods for constructing conformal nano-antireflective coatings with controllable thickness on the microstructures. The emphasis will focus on exploring the mechanism of conformally and uniformly depositing coating blocks, and the key factors controlling film thickness and morphology. Further, multifunctions such as anti-graffiti, anti-fingerprint, self-cleaning will be integrated in the prepared antireflective coatings. The relationship between film structure and antifouling performance will be investigated. It is expected to provide a new simple method to construct antireflective coatings for optical materials with microstructured surfaces.
