The Fabrication of Free-standing Photonic Crystal Films or Tape based on Porous Paper-based Media

Caption

This study demonstrates a paper-sacrifice-templated fabrication of flexible, freestanding, sandwich-structured photonic crystal films/tapes through a sequential process involving: (1) evaporation-induced self-assembly of PC layers, (2) top-side polymer encapsulation, (3) substrate peeling, and (4) bottom-side polymer encapsulation. The resulting PC films/tapes exhibit tunable iridescence, pretty durability, and universal adhesion to diverse substrates
