Carbon-containing thin film interference microspheres with non-iridescent structural color and preparation method
By coating the surface of polymer microspheres with inorganic films and then ablating them at high temperatures, non-iridescent carbon-containing thin film microspheres were prepared, solving the problems of angle dependence and particulate matter in structural color coatings and achieving a high-saturation, uniform structural color effect.

Abstract
The application relates to a carbon-containing thin film interference microsphere with non-iridescent structural color and a preparation method, and belongs to the field of new materials. The carbon-containing thin film interference microsphere with non-iridescent structural color is prepared by high-temperature calcination of polymer-inorganic hybrid microspheres; the polymer-inorganic hybrid microspheres are prepared by uniformly coating an inorganic thin film interference layer on the surface of polymer microspheres, and the average particle size is 300-1800 nm, and is further preferably 500-1000 nm. The non-iridescent submicron thin film interference microsphere structural color pigment has the advantages of bright color, small particle size and simple preparation method, and can be used as a novel structural color pigment.
