Facile fabrication of mechanically stable non-iridescent structural color coatings

The application of structural color materials is usually blocked by their iridescence, tendency to cracking and feeble mechanical properties. In this work, mechanically stable non-iridescent structural color coatings have been fabricated by the co-assembly of polydopamine-coated polystyrene nanoparticles (PS@PDA NPs) and chitosan (CS). The introduction of CS into the PS@PDA NPs assembly system greatly restrained the generation of cracks and...
