Copper nanowire (CuNW) is one of the most promising candidates for next-generation transparent conductive film (TCF). However, practical applications of CuNW are still limited by several drawbacks, including loose wire to wire junctions, poor resistance against oxidation, chemical and thermal damage. To concurrently address these urgent issues, highly conductive and stable TCF is prepared based on [email protected] core-shell NW networks by electrodeposition. The coated Ni shell can weld stacked NWs tightly, which decreases the sheet resistance from 513 to 15.8 Ohm/sq (at a transmittance of 88%), as well as improves the mechanical stability (1.03-fold resistance increase after 2000 cyclic bending). The [email protected] NW TCF exhibits excellent antioxidation performance after storing in atmospheric environment for 168 h. The passivation Ni shell also improvs the chemical and thermal stability. The [email protected] NW network keeps intact after 450 s H2O2 corrosion and heating at 400 °C for 30 min. Moreover, a flexible transparent heater was fabricated based on these TCFs, which shows excellent uniform heating performance and high response speed.

高稳定性透明导电膜的Cu @ Ni核壳纳米线网络的电沉积制备
铜纳米线(CuNW)是下一代透明导电膜(TCF)的最有希望的候选者之一。但是,CuNW的实际应用仍然受到几个缺点的限制,包括线对线的连接松散,抗氧化性,化学和热损伤性差。为了同时解决这些紧迫的问题,基于电沉积的[受电子邮件保护的]核壳NW网络制备了高导电性和稳定的TCF。镀镍的Ni壳可以紧密焊接堆叠的NW,从而将薄层电阻从513降低到15.8 Ohm / sq(透射比为88%),并提高了机械稳定性(2000次循环弯曲后电阻增加了1.03倍)。[受电子邮件保护] NW TCF在大气环境中存放168小时后,具有出色的抗氧化性能。钝化的镍壳也提高了化学和热稳定性。450 s H后,[受电子邮件保护的] NW网络保持不变2 O 2腐蚀并在400°C下加热30分钟。此外,基于这些TCF制备了柔性透明加热器,该加热器显示出出色的均匀加热性能和高响应速度。
