Structural colors have shown great promise as an alternative for the existing colorant-based pigments owing to their noticeable advantages, such as high brightness, durability and stability, and environmental safety. They may find potential applications in energy-efficient displays, high-resolution imaging, special effect coatings, and building-integrated photovoltaics. The structural colors can be produced by exploiting optical resonances in various resonators, which can be either 3D, 2D or 1D structures. To enable scalable manufacturing, layered structures can be designed, and can be easily made by additive deposition processes. A new type of flexible transparent conductor based on ultra-thin Ag film was demonstrated. It can be designed to have even greater transparency than the PET substrate itself. Such transparent conductors could find wide range of applications in flexible displays, touch screens and transparent EM shielding, and can be manufactured in large area format by industrial roll sputtering processes.
