In order to facilitate the design freedom for the implementation of textile-integrated electronics, we seek flexible transparent conductive electrodes (TCEs) that can withstand not only the mechanical stresses encountered during use but also the thermal stresses of post-treatment. The transparent conductive oxides (TCO) typically used for this purpose are rigid in comparison to the fibers or textiles they are intended to coat. In this paper, a TCO, specifically aluminum-doped zinc oxide (Al:ZnO), is combined with an underlying layer of silver nanowires (Ag-NW). This combination brings together the advantages of a closed, conductive Al:ZnO layer and a flexible Ag-NW layer, forming a TCE. The result is a transparency of 20-25% (within the 400-800 nm range) and a sheet resistance of 10 Ω/sq that remains almost unchanged, even after post-treatment at 180 °C.
为了便于在实现集成纺织品的电子产品时拥有设计自由度，我们需要能承受使用过程中遇到的机械应力以及后处理热应力的柔性透明导电电极（TCE）。与它们打算包覆的纤维或纺织品相比，通常用于此目的的透明导电氧化物（TCO）是刚性的。在本文中，一种TCO，具体为铝掺杂氧化锌（Al:ZnO），与银纳米线（Ag-NW）底层相结合。这种组合兼具封闭导电的Al:ZnO层和柔性Ag-NW层的优点，形成了一种TCE。结果是在400 - 800纳米范围内透明度为20 - 25%，方阻为10 Ω/sq，即使在180°C后处理后也几乎保持不变。
