随着可拉伸电子器件向更高集成密度和更小特征尺寸发展，作为这些电子器件结构骨干的可拉伸导体也必须相应缩小。然而，使用现有导电材料在高分辨率下同时实现高拉伸性和高电导率仍然是一个挑战。在此，通过材料设计和界面工程，我们开发了一种硫醇功能化导电聚合物/金混合叠层，该叠层可使用标准光刻技术图案化至4微米线宽，同时保持高拉伸性、类金属电导率（>40,000 S/cm）和环境稳定性。利用这一能力，我们展示了基于网格的可拉伸透明电极，其品质因数超越了氧化铟锡，以及一个由可拉伸线条互连的1000像素每英寸图像。这项工作有助于拓宽下一代功能软电子器件的应用范围，包括电子皮肤和生物电子学。
英文摘要
As stretchable electronics advance toward higher integration density and finer feature sizes, stretchable conductors, which serve as the architectural backbone of these electronics, must be scaled down accordingly. However, achieving both high stretchability and high electrical conductivity at high resolution remains a challenge using existing conductive materials. Here, through material design and interfacial engineering, we develop a thiol-functionalized conducting polymer/gold hybrid stack that can be patterned down to 4 micrometer linewidths using standard photolithography, while maintaining high stretchability, metal-like conductivity (>40,000 S/cm), and environmental stability. Leveraging this capability, we demonstrate grid-based stretchable transparent electrodes that surpass the figure-of-merit of indium tin oxide, as well as a 1000-pixel-per-inch image interconnected with stretchable lines. This work helps to broaden the scope of next-generation functional soft electronics, including e-skins and bioelectronics.
