This study reports a scalable and easily fabricated Ag nanowires bundle micro-meshes embedded in polyimide conducting film, which exhibits high thermal stability, low sheet resistance variation, and good corrosion and deformation resistance. As an electrical heater, the conducting film can achieve high temperature with a fast thermal response time, and it also maintains good heating stability under bent conditions.
To realize high performance flexible transparent electronics with extreme environmental adaptivity, Ag nanowires (Ag NWs) electrodes should simultaneously meet the requirements of high-temperature tolerance, chemical and mechanical robustness. Herein, a scalable Ag NWs bundle micro-meshes embedded in polyimide (Ag BMs/ePI) conducting film via a facile spray coating and transfer method is reported. Due to the synergistic effect of bundle micromesh and embedded architecture, the Ag BMs/ePI electrode exhibits high thermal stability (370 degrees C and 400 degrees C under ambient and nitrogen atmosphere conditions, respectively), low sheet resistance variation (<4%), good corrosion and deformation resistance. As an electrical heater, the Ag BMs/ePI can achieve similar to 204 degrees C with the fast thermal response time of similar to 8 s at 8 V, and exhibits good heating stability under bent condition. This work offers a promising platform for the emerging flexible transparent electronics to adapt extreme environments, especially for those devices which require high-temperature processing.
