Silver nanowire (Ag NW)/PDMS transparent conductive films (TCFs) are promising for flexible electrothermal devices because of their conductivity, transparency, flexibility, and biocompatibility. In this study, Ag NW network morphology was controlled by microstructure engineering to fabricate TCFs with different architectures. The results reveal that electrothermal performance is governed not only by sheet resistance, but also by network uniformity, junction organization, and conductive pathway connectivity. In particular, the scaffolded cross-linked network forms uniform and continuous pathways, enabling efficient and homogeneous Joule heating. The optimized film rapidly reaches about 41 °C at 0.6 V and exhibits high electrothermal efficiency with excellent thermal cycling stability. This study provides a structural design guideline for low-power, high-efficiency flexible electrothermal TCFs.
