Abstract

The invention discloses a structural color film stabilizer and a preparation method thereof, and relates to the technical field of structural color stabilizers. A graphene-polydopamine composite material is adopted as a black light absorbing substance; on one hand, the color contrast ratio of a structural color film is improved; at the same time, due to the diversity of a graphene-polydopamine composite structure, the angle of the structural color film can be easily adjusted, the angle dependency for observing the structural color film is reduced, meanwhile, by adjusting the amounts of added ethanol and surfactant, the volatile property of a solvent and contracting performance of colloidal microspheres of the structural color film can be adjusted, and thus the stability of the structural color film is improved.

Description

technical field [0001] The invention relates to the technical field of structural color stabilizers, in particular to a structural color film stabilizer and a preparation method thereof. Background technique [0002] In addition to pigments and pigments, the colors we are familiar with in nature also have structural colors. In terms of color formation mechanism, different from the intramolecular effect of pigment color, structural color is the result of the interaction between the microscopic structure of the substance itself and light. At present, the main method of artificially preparing structural color materials is to use colloidal microspheres with good monodispersity as structural units to self-assemble to prepare brightly colored structural color film coatings, and then use vertical deposition, gravity sedimentation, and dip coating deposition as the most typical methods. The colloidal assembly method prepared the structural color coating film. [0003] When the app...
