Conducting metal nanowires can be assembled into thin films for flexible electronics and optoelectronics applications including transparant electrodes, nanocircuits, and electronic skin, however, the junction resistances and low aspect ratios still limit its performance. Herein we report high quality silver nanofibers (AgNFs) synthesized by a gas assistant solution spinning method. Compared with traditional Ag nanowires that usually have lengths below 100 mu m, AgNFs are infinitely long and can be easily assembled into large-scale 2D and 3D flexible conductors with fused junctions between nanofibers. The AgNF networks showed high transparency, low sheet resistance (e.g, 6 Omega sq(-1) at similar to 97% transparency), and high flexibility as transparent electrodes, whereas the 3D AgNF sponge could be used as a deformable and robust 3D conductor.
