Metal nanotrough embedded colorless polyimide films: transparent conducting electrodes with exceptional flexibility and high conductivity

摘要

Reliable performances with a long lifetime are the most important factors of transparent conducting electrodes (TCEs). Here, we report a new synthesis strategy for high-performance TCEs based on the fusion of a polyimide (PI) substrate and silver layer-coated PI nanofibers. Due to the successful fusion of the substrate into the core without immiscibility, the as-synthesized TCEs showed excellent performances (a sheet resistance of 1.33 Omega sq(-1) and a total optical transmittance of 88) even after 100 000 bending cycles at a bending radius of 1.75 mm.
