Biopolymer photonic crystals and method of manufacturing the same

摘要

A method of manufacturing a biopolymer photonic crystal includes providing a biopolymer, processing the biopolymer to yield a biopolymer matrix solution, providing a substrate, casting the matrix solution on the substrate, and drying the biopolymer matrix solution to form a solidified biopolymer film. A surface of the film is formed with a nanopattern, or a nanopattern is machined on a surface of the film. In another embodiment, a plurality of biopolymer films is stacked together. A photonic crystal is also provided that is made of a biopolymer and has a nanopatterned surface. In another embodiment, the photonic crystal includes a plurality of nanopatterned films that are stacked together.
