However, the lens aging and degradation still occurred after a long time of ultraviolet exposure. In this study, a free-UV absorbing anti-ultraviolet biodegradable transparent film were prepared from the bioinspired nano array structure of the surface layer of insects which could reflect specific wavelength of light. The desired pore size to reflect the specific wavelength could be calculated from the Bragg-Snell''s Law. Polystyrene (PS) nanosphere were synthesized by emulsifier-free emulsion polymerization, and different layers of opal array of the PS nanosphere were assembled by the Langmuir-Blodgett deposition method. Pouring the modified silk fibroin (SF) into the voids of the PS opal array, and removing the enclosed opal array from the SF surrounded PS array by solvent, then an anti-ultraviolet biodegradable transparent film with inverse opal structure was obtained.
