Claim 6:
7. A method for preparing the structurally stable composite structural chromogenic material according to claim 1, comprising the steps of:
building a first structural color layer by assembling an emulsion of micro-nanospheres having a solid content of 5% to 30% on a first thermoplastic polymer film;
covering the first structural color layer with a second thermoplastic polymer film;
building a second structure color layer on the second thermoplastic polymer film; covering the second structural color layer with a third thermoplastic polymer film;
building a second structural color layer by assembling an emulsion of micro-nanospheres having a solid content of 5% to 30% on a second thermoplastic polymer film; and
repeating, sequentially, the building step and the covering step until a pre-determined number of structural color layers are obtained,
and bonding the peripheral edges of all the thermoplastic polymer films are bond together using hot-press.
