Abstract
Process for forming a multi-layer electrochromic structure, the process comprising depositing a film of a liquid mixture onto a surface of a substrate, and treating the deposited film to form an anodic electrochromic layer, the liquid mixture comprising a continuous phase and a dispersed phase, the dispersed phase comprising metal oxide particles, metal alkoxide particles, metal alkoxide oligomers, gels or particles, or a combination thereof having a number average size of at least 5 nm.
