Antireflection coating AR-hard with UV-protective properties for polycarbonate

Polycarbonate (PC) is the chosen material for covers of automotive displays because it combines high transparency with high breaking strength. The requirements for coatings comprise an improvement of the scratch resistance and antireflection properties as well as high stability for challenging environmental conditions. A coating that involves all required properties has been developed and deposited onto PC by plasma-ion assisted deposition (Plasma-IAD).
