一种多色彩钴镍氢氧化物电致变色复合膜层的制备方法
By introducing V2O5 and constructing a MnO2 bonding layer into the Co(OH)2/Ni(OH)2 thin film, the problems of insufficient variable color and poor adhesion of the Co(OH)2/Ni(OH)2 electrochromic thin film were solved, realizing the preparation of multi-color and highly stable composite film layers and broadening the application range.

AI Technical Summary
Existing Co(OH)2/Ni(OH)2 electrochromic films have limited color options, lack vibrant colors, and exhibit insufficient adhesion to the substrate, thus affecting cycle stability.
By introducing V2O5 and MnO2 into Co(OH)2/Ni(OH)2 electrochromic films, and by controlling the preparation parameters of V2O5 and constructing an MnO2 bonding layer on the substrate, multi-color composite films were prepared using a simple cyclic voltammetry and electrodeposition method, thus optimizing the film structure and adhesion.
This enriches the variable color range of the thin film, extending it from blue-green to orange-red, improving the film's photoelectric properties and cycle stability, enhancing the adhesion between the film and the substrate, and strengthening its application potential in camouflage and stealth materials.
