Bio‐Inspired Unclonable Anti‐Counterfeiting Based on Random Patterns of Colloidal Crystal Flakes
Inspired by the random, colorful Turing patterns on the wings of the butterfly ( Papilio paris Linnaeus), unclonable anti‐counterfeiting based on interspersed structural colors has been developed by randomly dispersing colloidal crystal flakes (CCFs) into a functional polymeric matrix. The tiny shining CCFs exhib...
