The invention relates to the technical field of polymer functional materials and structural color optical materials, in particular to a preparation method of an amorphous structural color material based on temperature-responsive core-shell particles. The preparation method comprises the following steps: by taking silicon dioxide particles with polymerization functional groups on the surfaces as cores, coating poly N-isopropylacrylamide in situ by utilizing free radical polymerization to form a temperature-responsive core-shell structure; and then mixing with an auxiliary agent, and inducing short-range arrangement of particles on a heating substrate through solvent volatilization to form the amorphous structural color film. The prepared film shows color change at different temperatures, keeps color consistent at different observation angles, has good thermal responsiveness and low iridescence, and is suitable for the fields of temperature sensing, intelligent display, functional decoration materials and the like.

The utility model discloses a colorful optical film which can avoid complex process steps when being attached to a lens, and has the properties of wear resistance, corrosion resistance, falling prevention and the like. The colorful optical film comprises a first film layer, a second film layer, a third film layer, a fourth film layer and a fifth film layer which are sequentially stacked from top to bottom. The first film layer and the fifth film layer are protective films; the second film layer is a TAC reinforced film layer; the third film layer is a liquid crystal colorful reflecting layer; and the fourth film layer is a TAC white common layer, an anti-UV film, a polarizing film, a monochromatic film or a color-changing film. According to the utility model, the film material with the performances of dazzling color, wear resistance, corrosion resistance and the like is prepared by adopting the existing process and the existing material, the film material has certain flexibility, and compared with the traditional electroplating film which needs to be subjected to single-piece electroplating after being cut and bent by baking, the processing process is simpler, and the complicated steps and low yield of electroplating treatment piece by piece in the electroplating process are avoided.
