How to develop new dyeing technology has become an important issue in the field of environmental protection due to the factors that traditional coatings fade and pollute the environment.With the development of optical field and the progress of nanomaterials,structural color because of its pollution-free and high purity,has good application prospects.In this paper,the optical principle of MIM(Metal-Insulator-Metal)structure and metal nanoparticle structure color modulation are described.By combining the two methods,a multi-layer thin film structure was made of silver,aluminum oxide and gold.By changing the thickness of the film and the surface of the metal particles and morphology,we provide a method for the preparation of structure color under dual modulation.The method has the advantages of low cost,simple preparation process and high production efficiency and it is suitable for large area preparation.Based on the special optical properties of the system,the potential application of the system is analyzed.
