Fabrication of Moth-eye Antireflective Nanostructures via Oxygen Ion-beam Etching on a UV-curable Polymer

We report a low-cost, high-throughput process for fabricating moth-eye-like anti-reflector on curved surface. First, surface was made from UV-curable resin via UV imprinting. Then, the structures were formed directly polymer oxygen ion-beam etching. This produced flexible, transparent, and products with anti-reflective properties. The method avoids duplication, which is generally needed conventional fabrication. compared performance both flat lenses before after reflectance etching 150 s substantially 10% lower than that of non-etched usefulness this optical properties demonstrated.
