摘要 采用层接层自组装方法在FTO导电玻璃基片表面制备了Dawson型多酸(P2W18)与中性红(NR)的复合材料.采用紫外-可见吸收光谱、扫描电子显微镜、循环伏安扫描、计时电流法(CA)和计时电量法(CC)等对复合膜材料进行了表征.结果表明:多酸和中性红(NR)通过静电相互作用成膜,复合膜表面是均匀和平整的;复合膜的光反差为36.1%,着色效率为28.0cm2/C;实现了粉红色、淡紫色及深紫色的可调变颜色过程. The nanocomposite film comtainingDawson-type polyoxometalate(P2W18)and neutral red(NR)was prepared on FTO glass by the layer-by-layer self-assembly method(LbL).The fabrication,structure and performance were characterized by UV-vis spectroscopy(UV-vis),scanning electron microscopy(SEM),cyclic voltammetry(CV),chronoamperometric(CA)and chromocoulometry(CC).As a result,the fabrication of the film relies on electrostatic absorption and the surface morphology is smooth.Furthermore,the composite film displays adjustable colors and undergoes transitions from pink to light purple,then to dark purple,resulting in an optical contrast of 36.1% and a coloration efficiency of 28.0cm^2/C.
