AI Technical Summary
Existing electrochromic materials, when the composition ratio is not right, are prone to insufficient or excessive cross-linking, which affects the stability and adhesion of the film, making it difficult to transfer smoothly onto the transparent conductive layer, and the unsuitable thickness affects the effect and device size.
By optimizing the ratio of polyimide, crosslinking agent, electrochromic material and solvent, and combining it with a multilayer structure design, including the precise coating and attachment process of release film and transparent conductive layer, a stable electrochromic film is formed.
This method achieves smooth transfer and stability of the electrochromic film on the transparent conductive layer, ensuring the continuity and appropriate thickness of the film, and enhancing the electrochromic effect and the aesthetic value of the device.
