In this study, a magnetic assisted electrodeposition process was developed to fabricate a hybrid silver nanowire conductive film with excellent performance. In the two-step fabrication process, the primary conductive film was dip-coated with a low concentration of AgNW ink, which gives decent conductivity and extraordinary transmittance. It is worth noting that the highly diluted ink solution is superior to a high concentration of silver nanowire ink, which is prone to aggregate and hard to redisperse. Next, a magnetic assisted electrodeposition process was applied to in situ grow a secondary metallic layer onto AgNWs, leading to a much better conductivity while maintaining the high transmittance, which well reconciles the contradictive requirements between transmittance and conductivity. Especially, thanks to the magnetic tuning effect, a unique Ni protective layer was formed to achieve prominent adhesion on the substrate without embedding the structure into any material. The conductivity of the Ni/AgNW-based TCFs has no obvious change even after heating at 400 °C for 30 min, which is by far the best thermal stability ever reported. In addition, the excellent electrical and optical performances (a typical sheet resistance of ca. 9.8 Ω sq −1 at a transmittance of ca. 95.3%) outperformed most of the existing AgNW-based TCFs. Two devices, including an HITSZ pattern of LED lights and a nanoheater, were fabricated to demonstrate the feasibility and the outstanding performance. AgNW-Based TCFs derived from the electrodeposition of a metal in a magnetic field show excellent transmittance, conductivity, reliability and thermal stability.
