Phase-Separation Method Leads to Better AR Coating

Facebook X LinkedIn Email
Since the 1930s, it has been common practice to cover lenses with antireflection coatings to enhance the performance of devices that require the maximum transmission of light. Despite years of intensive research, broadband antireflection coatings are still limited by a lack of materials with low refractive indices. Now a research team from the Universitat Konstanz in Germany has pioneered a method based on the phase separation of a macromolecular liquid to produce nanoporous films. The researchers dissolved polystyrene and polymethyl methacrylate in a solvent, which they then used to...Read full article
