The invention relates to a functionalized structural color dye and preparation and application thereof, wherein an ultraviolet sunscreen material is modified on the surface of a monodisperse microsphere or coated in the shell layer of the monodisperse microsphere, and the preparation method comprises the following steps: modifying the ultraviolet sunscreen material on the surface of the monodisperse microsphere or coating the ultraviolet sunscreen material in the shell layer of the monodisperse microsphere to obtain a microsphere solution, diluting the microsphere solution to the concentration of 0.1-10wt%, uniformly dispersing by ultrasonic, and then self-assembling on a substrate to obtain the ultraviolet sunscreen material. The invention endows the structural color material with the ultraviolet sun-screening function, does not influence the optical property and the color and luster degree of the prepared structural color, and has broad-spectrum applicability to base materials with different compositions and microstructures; the method has the advantages of simple process, preparation cost saving, strong universality and good application prospect. |
