| Abstract Scope |
Silver nanowires (AgNWs)/PDMS nanocomposite transparent conductive films (TCFs) combine electrical conductivity, optical transparency, flexibility, and biocompatibility, making them promising for flexible electrothermal devices. In this study, Ag NW network morphology was controlled through microstructural design to fabricate TCFs with different architectures, and their optical, electrical, mechanical, and electrothermal properties were investigated. The electrothermal behavior of AgNW networks is not determined solely by sheet resistance, but is dependent on network uniformity, junction organization, and pathway connectivity. Particularly, the scaffolded cross-linked network forms uniform and continuous pathways, promoting efficient and homogeneous heating. It rapidly reaches ~41°C at an ultralow voltage of 0.6V and exhibits high heating efficiency of ~300 °C·cm2·W-1, together with excellent cyclic thermal stability. This enhancement is attributed to the uniform current distribution and effective junction-based heat generation enabled by microstructural control. This study reveals the structure-governed electrothermal mechanism and provides an effective pathway for designing low-power, high-efficiency flexible TCFs. |
