Transparent thermoplastic Bisphenol-A-polycarbonate (PC) holds an important position as material for optics as well as for automotive glazing. However, the soft and UV sensitive polymer surfaces need to be protected by coatings. For optical applications especially antireflective coatings are inevitable. A comprehensive understanding of complex interactions caused by ultraviolet radiation is a key factor for the development of coating strategies for PC. To protect the interface, optical coatings for PC were realized by incorporating organic absorbers and by exploiting interference effects. In addition, plasma etched nanostructures can be used on the inner surfaces of PC cover glass. The high transparent surfaces exhibit antireflective properties, non-fogging performance and high thermal stability.
