Abstract

Solution-processable electrochromic (EC) materials have been investigated widely for various applications, such as smart windows, reflective displays, and sensors. Among them, tungsten trioxide (WO) is an attractive material because it can form a film via a solution process and relative low temperature treatment, which is suitable for a range of substrates. This paper introduces the slot-die and electrostatic force-assisted dispensing (EFAD) printing for solution-processable methods of WO film fabrication. The resulting films were compared with WO films prepared by spin coating. Both films exhibited a similar morphology and crystalline structure. Furthermore, three different processed WO film-based electrochromic devices (ECDs) were prepared and exhibited similar device behaviors. In addition, large area (100 cm) and patterned ECDs were fabricated using slot-die and EFAD printing. Consequently, slot-die and EFAD printing can be used to commercialize WO based-ECDs applications, such as smart windows and reflective displays.

摘要

可溶液加工的电致变色（EC）材料已被广泛研究用于各种应用，如智能窗户、反射式显示器和传感器。其中，三氧化钨（WO）是一种有吸引力的材料，因为它可以通过溶液工艺和相对低温处理形成薄膜，适用于一系列基材。本文介绍了用于WO薄膜制备的溶液加工方法的狭缝模头和静电力辅助分配（EFAD）印刷。将所得薄膜与通过旋涂制备的WO薄膜进行比较。两种薄膜都表现出相似的形态和晶体结构。此外，制备了三种不同工艺的基于WO薄膜的电致变色器件（ECD），并表现出相似的器件行为。此外，使用狭缝模头和EFAD印刷制备了大面积（100平方厘米）和图案化的ECD。因此，狭缝模头和EFAD印刷可用于将基于WO的ECD应用商业化，如智能窗户和反射式显示器。
