Gyroid-structured nanoporous chitosan is successfully fabricated by templated crosslinking reaction using nanoporous polymer as a template. A multiple pore-filling process is developed for templated synthesis to give well-ordered nanoporous chitosan. Bio-mimicking from the structural coloration of butterfly wing structure, the nanoporous chitosan with gyroid texture is highly appealing in the application of high reflective materials for UV optical devices.
