Conductive fiber networks have both high transparency and high electrical conductivity, and thus is a new type of promising alternative for replacing In doped SnO₂ (ITO) used as transparent electrodes. Even though metal fibers possess high electrical conductivity, their properties sharply deteriorate when suffering oxidation or corrosion, which severely limits their applications. In this work, novel tungsten nitride (WN) fibers were firstly fabricated by electrospinning together with nitridation treatment. Patterning of WN fibers was further achieved by near-field direct writing method, and WN fiber based transparent electrodes were successfully assembled with high transparency, high electrical conductivity, as well as anti-oxidation and-corrosion ability. The electrical conductivity of WN fibers increased with the nitridation temperature, which reached 2189 S/cm at 900 ℃. Transparency and electrical conductivity of the WN fiber transparent electrode could be optimized through regulating its network structure. A high transparency above 94% and low sheet resistance of 6.0 Ω/sq was achieved when the spacing of the WN fiber network was 200 μm. This performance even exceeds that of the metal fiber transparent electrodes as previously reported. Furthermore, as compared with metal fibers, the WN fiber transparent electrode also exhibited outstanding anti-oxidation and -corrosion ability. Its sheet resistance only increased by 8% after oxidation at 160 ℃ for 16 h, and just 3% increase in the sheet resistance happend after corrosion in a solution with pH ranging from 1 to 13 for 1 min.
