光学表面涂覆一层薄层以改善光的透过率，在日常光学应用中以及在工业和科学仪器中普遍存在。镜片镀膜最早由弗劳恩霍夫于1817年发现，在20世纪30年代成为标准做法。尽管人们进行了大量的研究，但由于缺乏低折射率的材料，宽带增透膜的应用仍然受到限制。介绍了一种基于高分子液体的相分离来制备纳米多孔聚合物薄膜的方法，该方法可以产生具有高透光率的表面。
Optical surfaces coated with a thin layer to improve Light transmission are ubiquitous in everyday optical applications as well as in industrial and scientific instruments. Discovered first in 1817 by Fraunhofer, the coating of Lenses became standard practice in the 1930s. In spite of intensive research, broadband antireflection coatings are still limited by the Lack of materials with Low refractive indices. A method based on the phase separation of a macromolecular Liquid to generate nanoporous polymer films is demonstrated that creates surfaces with high optical transmission.
