The invention relates to a method for preparing a photonic crystal structure chromophoric material by a spraying method, which comprises the following steps: S1, preparing a nano microsphere assembly liquid for structural chromophoric by the spraying method, S2, modifying the surface of a base material: coating a special high-molecular polymer on the surface of the base material, and heating and curing to form a film to obtain the base material with a special high-molecular layer on the surface; s3, injecting the nano-microsphere assembly liquid into an ink fountain, and uniformly spraying on the surface of the base material with the special polymer layer obtained in the S2; and S4, heating the sprayed base material, and completing the assembly of the nano-microspheres, the activation and migration of interface molecules of the polymer layer and the stable curing of the photonic crystal to obtain the photonic crystal structure chromogenic material with the obvious iridescent effect. 本发明涉及一种喷涂法制备光子晶体结构生色材料的方法，
