Self-assembly of colloidal microspheres into ordered arrays is an effective way to prepare structural color materials based on photonic crystals. However, the interaction between microspheres is weak and the structure is easily destroyed by external forces, which is the main obstacle in their practical application. In this article, polyvinylidene fluoride is filled in the gaps of three-dimensional photonic crystals of PS@SiO₂ to lock the ordered arrays benefiting from its mechanical stability and tensile resistance, thus constructing a novel structural color system with stable structure and flexibility. After 100 friction tests, the structure and color of the system remains stable. At the same time, the system is easy to pattern, and has excellent tensile resistance and flexibility. The tensile fracture strength of the system reaches 22.28 MPa, and the fracture strain rate is 28.49%. In addition, the microstructure is still stable after 100 bending tests.
