电致变色是指在电场作用下，材料发生可逆的变色现象。电致变色实质是一种电化学氧化还原反应，反应后材料在外观上表现出颜色的可逆变化。电致变色材料是指在外电场及电流的作用下，可发生色彩变化的材料即为电致变色材料，其本质是材料的化学结构在电场作用下发生改变，进而引起材料吸收光谱的变化。
具有实用价值的电致变色材料必须具备颜色变化的可逆性、颜色变化的方便性和灵敏性、颜色深度的可控性、颜色记忆性、驱动电压低、多色性和环境适应性强等特点。目前，现有技术中电致变色材料已基本具备上述性质，电致变色材料的特点和优势促使各种电致变色器件的研制和开发。
现有技术中，在制备电致变色器件时需要使用导电基体贴合变色材料，贴合完成后进行紫外光固化，固化完成后对电致变色器件进行收卷或者分切存储，但此时所得电致变色器件通常不具备隔绝水氧的能力，容易被空气中的水氧影响而造成变色不均匀的现象；同时，此时的电致变色器件仅依靠变色材料的上下表面与导电基体进行粘结，容易产生脱膜的现象。
