Silver nanowires (AgNWs) with the length and diameter of 25–35 μm and 25–35 nm, respectively, were prepared via a polyol reduction process using FeCl₃ and NaBr as reaction inhibitors. The molar ratio of FeCl₃ to NaBr has an influence on the yield of the product, but has little influence on the morphology of the product. Transparent conductive AgNWs films were fabricated on a glass slide and the optoelectronic and electrothermal properties of the film were investigated. The experimental results reveal that AgNWs heated at 25–170°C remained intact, and fused into discontinuous segments after heated at 200°C; and AgNWs films have good conductivities (51.2 to 20.5 Ω sq⁻¹), excellent transmittance values (96.3 to 95.7%), and low surface roughness values (12.7 to 18.3 nm). The transparent AgNWs film heaters show fast heat response to reach its steady-state temperature and good electro-thermal conversion behaviour at low input voltages.
