Abstract

Conductive metal films are patterned into transparent metal nanowire networks by using electrospun fibers as a mask. Both the transmittance and sheet resistance (6 Ω/□ at 83% transmittance and 24 Ω/□ at 92% transmittance) of the metal nanowire-based electrode out-perform commercial indium doped tin oxide (ITO) electrodes. The metal nanowire-based transparent electrodes were fabricated on both rigid glass and flexible polyethylene terephthalate (PET) substrates. In addition to state of art performance, the transparent electrodes also exhibit outstanding toughness. They can withstand repeated scotch tape peeling and various bending tests. The method for making the metal nanowire is scalable, and a touch screen on flexible substrate is demonstrated.

摘要

通过使用静电纺丝纤维作为掩模，将导电金属膜图案化为透明金属纳米线网络。基于金属纳米线的电极的透光率和方阻（在透光率为 83%时为 6 Ω/□，在透光率为 92%时为 24 Ω/□）均优于商用掺锡氧化铟（ITO）电极。基于金属纳米线的透明电极被制造在刚性玻璃和柔性聚对苯二甲酸乙二醇酯（PET）基底上。除了达到现有技术的性能水平外，透明电极还具有出色的韧性。它们可以承受反复的透明胶带剥离和各种弯曲测试。制造金属纳米线的方法具有可扩展性，并展示了在柔性基底上的触摸屏。
