通过ZrO_2膜层与NiOx，WOx膜层的不同组合，在液态电解质下，测得不同电致变色膜系的电化学特性及相应着、脱色状态的光透射性能。证明了ZrO2膜层具有导通离子而隔断电子的离子导体层特性，并对NiOx膜层的变色机制进行了探讨。用X射线衍射方法对不同状态下NiOx，WOx薄膜的物相分析表明：电致变色反应中的阳离子注入膜层，使薄膜向有序化排列变化，共产生晶格类型的转变。 Through the different combinations of ZrO_2, NiOx and WOx films, the electrochemical properties of the different electrochromic films and the corresponding light-transmission properties of the bleached state were measured under the liquid electrolyte. It is demonstrated that the ZrO2 film has the characteristics of conducting ion and blocking electrons, and the mechanism of discoloration of NiOx film is also discussed. The phase analysis of NiOx and WOx films by X-ray diffraction shows that the cation is injected into the film in the electrochromic reaction to change the orderly arrangement of the films and cause the transformation of the lattice types.
