An electrochromic device (10) incorporates a reversibly colour-changing organic polymer film (20) as part of the display electrode. The display polymer film (20) is capable of undergoing reversible oxidation and/or reduction to a charged, coloured, conductive state. Upon reversing the charge, the polymer returns to its virgin colour. The display films are comprised of linear fused heterocyclic ring systems, optionally with connecting units, or linear monocyclic ring systems and connecting units. The device requires low currents to operate and switch from the virgin state to the coloured state. It also can optionally be operated to exhibit several colours.
一种电致变色装置(10)将可逆变色有机聚合物薄膜(20)作为显示电极的一部分。 显示聚合物薄膜(20)能够进行可逆氧化和/或还原,变成带电、有色、导电的状态。 一旦电荷反转,聚合物就会恢复原色。 显示薄膜由线性融合杂环环系统(可选择带连接单元)或线性单环环系统和连接单元组成。 该装置只需较低的电流即可运行并从原色状态切换到有色状态。 它还可选择运行以显示多种颜色。
