Inspired by the porous scale of the bright white beetle Cyphochilus, a polymerization-induced phase separation method is proposed to fabricate bioinspired high-scattering polymer films with porous structures. With an optimized formulation, the porous films with a mean pore size of similar to 200 nm feature a broadband reflectance of similar to 71% at a thickness of 16 mu m and are measured to have a transport mean free path of similar to 3 mu m. The porous films with high reflectivity enable the application on light-emitting diodes and have great potential in other similar optoelectronic fields.
