In this study, low-voltage, printed, ion gel-based electrochromic devices (ECDs) were successfully fabricated. While conventional dispensing printing provides irregularly printed electrochromic (EC) gels, we improved the adhesion between the printed gel and the substrate by applying an external voltage. This is called electrostatic-force-assisted dispensing printing. As a result, we obtained well-defined, printed, EC gels on substrates such as indium tin oxide-coated glass. We fabricated a gel-based ECD by simply sandwiching the printed EC gel between two transparent electrodes. The resulting ECD, which required a low coloration voltage (∼0.6 V), exhibited a high coloration efficiency (η) of 161 cm²/C and a large transmittance contrast (∼82%) between the bleached and colored states at −0.7 V. In addition, electrostatic-force-assisted dispensing printing was utilized to fabricate directly patterned ECDs.

低压显示器用电致变色胶的静电力辅助点胶印刷

在这项研究中，成功​​地制造了低压，印刷的，基于离子凝胶的电致变色器件（ECD）。尽管传统的点胶印刷提供不规则印刷的电致变色（EC）凝胶，但我们通过施加外部电压来改善印刷的凝胶与基材之间的粘合力。这称为静电力辅助点胶打印。结果，我们在诸如氧化铟锡涂层的玻璃之类的基材上获得了定义清晰的印刷EC凝胶。通过简单地将印刷的EC凝胶夹在两个透明电极之间，我们制作了基于凝胶的ECD。所需的低着色电压（〜0.6 V）的所得ECD表现出161 cm ²的高着色效率（η）/ C，在-0.7 V时的漂白状态和着色状态之间的透射率对比度大（约82％）。此外，静电力辅助点胶印刷被用来制造直接图案化的ECD。
