Low refractive index optical materials are critical components for next-generation, flexible, and responsive optical and optoelectronic devices, such as imaging systems, optical circuits, optical fibers, and waveguides. (1,2) Low refractive index materials are typically fluorinated compounds due to the low atomic polarizability of fluorine.

Elastic broadband antireflection coatings for flexible optics using multi-layered polymer thin films Yineng Zhao, Ni Huo, Sheng Ye and Wyatt E Tenhaeff Abstract Flexible optics and optoelectronic devices require stretchable and compliant antireflection coatings (ARC). Conventional optical coatings, typically inorganic thin films, are brittle and crack under strain, while porous or patterned surfaces often lack environmental endurance and/or involve complex processing.
