The invention relates to a method for preparing a butterfly wing/colloid crystal microsphere composite structural color film by a vertical deposition method, and belongs to the technical field of structural color film preparation. The butterfly wing with periodic structure was selected as a template, and the surface of the butterfly wing was pretreated; the colloidal crystal microsphere dispersion liquid was prepared and ultrasonically dispersed to make it in a uniformly dispersed state; after the butterfly wing was cut, it was placed vertically In the petri dish, slowly add the microsphere dispersion to completely submerge the butterfly wings, then place the petri dish in a constant temperature and humidity box, and assemble it by vertical deposition method. After the solvent is completely evaporated, butterfly wings/colloidal crystals are obtained The microsphere composite structure achieves specific color rendering effects in different viewing directions. The invention also discloses a batch preparation method of the film. The invention can realize structural color display with wide color gamut, narrow band gap, high brightness and special color rendering effect, and not only has important scientific research value, but also has great application value. |
