Flexible transparent conducting composite films using a monolithically embedded AgNW electrode with robust performance stability

Significance Statement

Transparent conducting electrodes (TCEs) based on random networks of silver nanowire (AgNW) are considered the most promising candidate for replacing indium tin oxide (ITO) due to their advantages of excellent opto-electrical performance, superior flexibility, and large-area processability coupled with low-cost solution processes. However, weak thermal/oxidation stability of AgNW TCE has been posed as the most critical drawback for its viable use. In this work, high performance AgNW composite (AgNW-GFRHybrimer) film was fabricated using surface-embedded AgNW network as a TCE and glass-fabric reinforced hybrid film as a thermally robust substrate. Thermal, oxidation, and chemical stability of AgNW-GFRHybrimer film were investigated to demonstrate the potential of the hybrid conducting film as a robust electrode platform for thin-film optoelectronics.

Abstract

We report on the performance of an all-in-one flexible hybrid conducting film employing a monolithically embedded AgNW transparent electrode and a high-performance glass-fabric reinforced composite substrate (AgNW–GFRHybrimer film). Specifically, we perform in-depth investigations on the stability of the AgNW–GFRHybrimer film against heat, thermal oxidation, and wet chemicals to demonstrate the potential of the hybrid conducting film as a robust electrode platform for thin-film optoelectronic devices. With the ease of large-area processability, smooth surface topography, and robust performance stability, the AgNW–GFRHybrimer film can be a promising platform for high-performance optoelectronic devices.
