摘要:

在氧化铟锡透明导电玻璃(ITO)电极上电化学聚合依次得到聚4,4',4″-三[4-(2-联噻吩基)苯基]胺(PTBTPA)和聚3,4-乙烯二氧噻吩(PEDOT)薄膜, 从而可控制备出叠层复合薄膜. 由红外光谱(FTIR)和场发射扫描电镜(SEM)表征了复合薄膜. 紫外-可见吸收光谱和电化学测试结果表明, 相对于PTBTPA薄膜(中性态橙色到氧化态深灰色)与PEDOT薄膜(中性态深蓝色到氧化态浅蓝色)的颜色变化, 叠层复合薄膜在不同的电压下能够展现出从橙色→蓝色→墨绿色的颜色变化, 并保持了较好的电化学活性和光学对比度. 这主要源于中性态吸收光谱和颜色显示互补的电致变色材料的选择. 本文提供了一种简单有效的制备多色乃至全色显示的电致变色材料的方法, 该方法同样适用于其它聚合物电致变色材料体系.

Abstract:

Two electrochromic polymers,poly(3,4-ethylenedioxythiophene)(PEDOT) and poly{4,4',4″-tris[4-(2-bithienyl)pheny]amine}(PTBTPA)with different neutral absorption spectra and the complementary colors were synthesized via electrochemical polymerization method, respectively. Then the composite film with the laminated structure was controllably prepared by adjusting the electrochemical polymerization parameters. FTIR spectra and SEM images indicate that the laminated composite film is obtained. UV-Vis spectra and electrochemical measurements demonstrate that the composite film exhibits a noticeable electrochromism with reversible color changes from orange, blue to dark green, and maintains good electrochemical activity and optical contrast compared to those of the pristine PTBTPA film and PEDOT film. This work is to provide a simple and efficient method to build the laminated composite structure for achieving multicolor or even full-color electrochromic materials, which is also suitable for other electrochromic polymer systems.
