| 摘 要： | 为了提高WO3纳米粒子薄膜的光学对比度,利用层接层自组装方法,将Keggin型结构的磷钨酸盐H3α-PW12O40]与WO3纳米粒子复合,制备PEI/PW12/PEI/WO3]20复合膜.采用扫描电镜、紫外光谱和电化学工作站对复合膜的形貌及电致变色性能进行研究,结果表明:该复合膜与单纯的WO3纳米粒子薄膜相比,光学对比度提高了117.28%,且这种复合膜提供了较大的H+扩散系数,可以获得更好的电致变色性能.

| Abstract: | In order to improve the optical contrast of the WO3 nanoparticle film, the film with the Keggin-type phosphotungstate cluster H3α-PW12O40] and WO3 nanoparticles were prepared by layer-by-layer(LbL) method, and characterized by scanning electron microscopy, UV-Visble spectra(UV-Vis), and electrochemical workstation. Compared with the pure WO3 nanoparticle film, the optical contrast of the composite film was increased by 117.28%, and this composite film provides a large H+ diffusion coefficient for better electrochromic performance. |
