为了提高薄膜[PEI/P5 W30]30的电致变色性能,将具有大的二维尺寸和良好导电性的氧化石墨烯引入该薄膜中.通过层层自组装(LBL)技术构筑了基于盘状多酸K12.5Na1.5[NaP5W30O110]·1SH2O(P5W30)、氧化石墨烯(GO)的复合薄膜[PEI/P5 W30/PEI/GO]30(PEI:聚乙烯亚胺),并利用UV-Vis光谱对薄膜的组成及增长进行监测;通过原子力显微镜对薄膜的表面形貌进行考察,利用循环伏安法对薄膜电化学氧化还原性质进行研究;薄膜在外加氧化还原电位下呈现出无色/蓝色的可逆变化,电致变色响应时间在10 s以内;此外,薄膜在阶跃电位0.75 V/-0.75 V下循环150次,电致变色性能没有明显减弱,体现了薄膜良好的电致变色可逆性.氧化石墨烯的引入使薄膜[PEI/P5 W30/PEI/GO]30呈现出响应速度快、抗电疲劳强的电致变色性能,将在电致变色器件领域有广阔的应用前景.
