Synthesis and sintering of AgNWs@PVP core–shell structures for improved transparent electrodes

Abstract

The majority of the current composite core–shell structure preparation and sintering processes applied to silver nanowire transparent electrodes are impractical for large-scale industrial production and primarily emphasize macroscopic performance parameters, with limited insights into the underlying sintering mechanism. This study presents a simple synthesis of AgNWs@PVP core–shell structures and investigates the effects of sintering temperature and time on their morphology. The morphology of AgNWs@PVP core–shell structures during sintering was systematically analyzed using characterization techniques, such as transmission electron microscopy and scanning electron microscopy. Subsequently, a comprehensive understanding of its sintering mechanism was summarized. This provides theoretical foundation for the preparation of AgNWs-based core–shell structures and high-temperature sintering based on core–shell structures.
