Here we present the preparation of a conductive adhesive electrode (CAE) for attachable electrochromic devices (ECDs). A photo-curable type of acrylic adhesive film was used as a substrate, and a smooth electrode was obtained with an overcoat of PEDOT:PSS onto pre-formed silver nanowire networks. By examining various compositions, the transmittance and electrical conductivity, with the resulting figure of merit ($FoM$) value, were optimized. The ECDs were fabricated by spray-coating a prepared EC gel layer composed of dihexyl viologen hexafluorophosphate, poly(vinylidene fluoride-co-hexafluoropropylene), and 1-butyl-3-methylimidazolum bis(trifluoromethylsulfonyl)imide. The electrochromic properties of the attachable ECDs were investigated in terms of cyclic voltammetry (CV), spectroelectrochemistry, and kinetic stability. The ECD started coloration at −0.9 V and was completely colored at −1.7 V, with the transmittance difference estimated to be 71.9%. The coloration efficiency was 213.7 cm²/C, and the cyclic stability was maintained after 2000 s with a change of less than 5%. Besides, a textile ECD was prepared by attaching an attachable ECD onto cotton fabric, which exhibited a reflectance difference of 17.8% at 604 nm and a color difference of 71.75 in terms of the chromaticity coordinates. These results suggest a promising platform for attachable electrochromic devices capable of exhibiting stable and noticeable color changes on any solid surface.

在这里，我们介绍用于可附着电致变色器件（ECD）的导电粘合电极（CAE）的制备。使用可光固化型丙烯酸类粘合剂膜作为基材，并在预先形成的银纳米线网络上覆盖PEDOT：PSS涂层，从而获得光滑的电极。通过检查各种成分，透射率和电导率，得出品质因数（$FØ\mathrm{中号}$）值，进行了优化。通过喷涂制备的EC凝胶层来制备ECD，该EC凝胶层由六氟磷酸二己酯，六氟乙烯-六氟丙烯共聚物和1-丁基-3-甲基咪唑双（三氟甲基磺酰基）酰亚胺组成。根据循环伏安法（CV），光谱电化学和动力学稳定性研究了可附着ECD的电致变色性质。ECD在-0.9 V时开始着色，并在-1.7 V时完全着色，透射率差估计为71.9％。着色效率为213.7 cm ²/ C，并且在2000 s后保持循环稳定性，变化小于5％。此外，通过将可附着的ECD附着到棉织物上来制备纺织品ECD，该棉织物在604nm处表现出17.8％的反射率差，并且在色度坐标上表现出71.75的色差。这些结果表明，可附着电致变色器件有希望的平台能够在任何固体表面上表现出稳定且明显的颜色变化。
