On the basis of the excellent performance of organic-inorganic composite one-dimensional photonic crystals and study method of their flexible films, and the principle of transfer printing, this project innovatively fabricates a kind of organic/inorganic composite one-dimensional photonic crystals with structural colors for coloration and printing of fabrics. A transfer printing method is designed for realizing application of the structural color materials on soft fabrics, and the related properties and mechanism will be studied. The controllable preparation of low-refractive-index polymer and high-refractive-index inorganic oxide sols will be studied and realized, and composite one-dimensional photonic crystals with brilliant structural colors will be assembled on low-surface-energy flat substrates through layer-by-layer assembly. The assembly mechanism and the relationship of the material structures and their optical, mechanical and thermal properties will be confirmed. Safe and stable assembly system and color modulating mechanism will be set up, and the advantageous performance of the organic and inorganic materials in one-dimensional photonic crystal assembly will be combined. The effect of the properties of porosity, transfer printing media, characteristics of polymer self-connection to form films and structures of the fabrics on transfer printing effects will be confirmed and transfer printing of the structural colors from low-surface-energy rigid flat substrates to soft fabrics will be implemented. Key scientific and technical problems in coloration and printing of structural colors on textiles will be solved from the studies of the material design, preparation, assembly, follow-up process and the related mechanism.
