Abstract
polystyrene (PS) were reacted at 50 °C for 10 min to prepare PS@PCA-Cu(ii) core-shell microspheres through rapid oxidative polymerization of CA coated PS of different particle diameters. The amorphous photonic crystal structure was self-assembled through thermal assisted-gravity sedimentation, resulting in structural color nanomaterials with soft and uniform color, no angle dependence, stable mechanical fastness and excellent UV resistance.
