Abstract
Flexible electronics demand conductive films with high stability and conductivity. However, silver nanowires (AgNWs) face challenges like agglomeration and inconsistent morphology. In this study, AgNWs were synthesized via a two-step process: (1) preliminary growth using a glass fiber template and polyol method (diameter: 0.2–0.4 μm, length: 1–6 μm), and (2) secondary growth by mixing AgNWs with PVA solution followed by heat treatment. The secondary growth enhanced nanowire dimensions (diameter: 5–7 μm, length: 100–200 μm) and conductivity. The optimized film exhibited stable resistance (4 MΩ) after 5000 bends (90° and 180°) and achieved optimal performance at 100 °C/30 min. This method provides a scalable solution for flexible electronics.
