This report presents the improved mechano‐electric sustainability of Ag NWs network with enhanced crystallinity (c‐Ag NW) based on the systematic bending‐fatigue study of Ag NWs network and its application toward electronic device built on patterned electrode. First, the mechano‐electric stability of Ag NWs network film is found to be highly associated with their crystalline structural deformation, i.e., defects or dislocation density by externally applied strains. Based on this result, c‐Ag NWs are prepared by the solution based thermal annealing at 70 °C and integrated into c‐Ag NWs network film. By analyzing crystalline structures and nano‐morphologies, as‐formed c‐Ag NW network film exhibits enhanced crystallinity and reduced dislocation density. In the bending fatigue tests under application of strain (6.7%, bending radius: 1 mm) during the 200 000 cycles, c‐Ag NWs network film shows highly reduced (>500%) resistance change (ΔR/ΔR_o: 45%) than that of pristine Ag NW network film (ΔR/ΔR_o: 241%). In the application of c‐Ag NW network toward patterned electrode, the electrode demonstrates the comparable electrical property (9.41 kΩ) to that of ITO based one (8.01 kΩ) despite the reduced number of nanowires in 6 µm neck diamond electrode pattern.

本报告基于对Ag NWs网络的系统弯曲疲劳研究及其在基于构图电极的电子设备中的应用，提出了具有增强结晶度（c-Ag NW）的Ag NWs网络改善的机电可持续性。首先，发现Ag NWs网络膜的机电稳定性与它们的晶体结构变形高度相关，即外部施加的应变导致的缺陷或位错密度。根据此结果，可通过基于溶液的70 °C热退火制备c-Ag NW C并集成到c-Ag NW网络膜中。通过分析晶体结构和纳米形态，形成的c-Ag NW网络膜表现出增强的结晶度和降低的位错密度。在应变下（6.7％，弯曲半径为1mm）的应用程序中的弯曲疲劳试验中的200个000循环，C的Ag纳米线网络电影欣赏高度还原的（> 500％）的电阻变化（Δ - [R / Δ - [R _ø：45 ％）比原始的Ag NW网络膜（Δ - [R / Δ - [R _ø：241％）。在C-银NW网络朝图案化电极的应用中，电极演示相当电气特性（9.41ķ Ω），以基于ITO酮（8.01 k的Ω尽管在6纳米线的数目减少） μ米颈部金刚石电极图案。
