Abstract: A structurally stable composite structural chromogenic material and a preparation method thereof are provided. The structurally stable composite structural chromogenic material is formed by stacking a transparent thermoplastic polymer and a structural chromogenic material layer by layer and then thermally bonding the peripheral edges of the polymer into a whole, and the upper surface layer and the lower surface layer of the material are both thermoplastic polymers. The molded composite structure has relatively obvious structural color and good mechanical strength.
