This project designs to construct hollow photonic crystals by using TiO2, ZnO, ZnS and ZrO2 hollow microspheres as templates, rutile hollow TiO2 microsphere template as an example, and hydroxypropyl methyl cellulose and acrylate polymer composite with adjustable mechanical properties or wettability as filling materials. The preparation methods of the hollow inorganic microspheres with uniform particle size, regular morphology and good dispersion are designed and studied; the assembly methods of large-scale hollow microspheres photonic crystals without cracks are investigated; the hydroxypropyl methyl cellulose and acrylate polymer composite filling materials with adjustable mechanical properties or wettability are designed and explored; rutile TiO2, ZnO, ZnS and ZrO2 photonic crystals with brilliant structural colors and controllable properties are researched; and the performance regulation schemes and application feasibility are established to provide theoretical basis and technical feasibility for the use of the hollow photonic crystals as new pigment materials. This project will provide a theoretical and technical basis for the development of new pigments with a small amount of chemical substances, and simple chemical and physical processes, which will meet the requirements for both national environmental protection policies and market applications.
