Ink formulation of functional nanowires with hyperbranched stabilizers for versatile printing of flexible electronics.

ABSTRACT: Functional nanowire ink formulations require elaborate control over their composition, rheological properties, and fluidic properties to optimize their printing processes. They also require harsh post-fabrication treatments to maximize the performance of the resulting printed flexible devices, making it challenging to uniformly deposit nanowire-based architectures and ensure device reproducibility and scalability. Here, we propose a strategy for developing silver nanowire (AgNW) ink formulations, where hyperbranched molecules (HPMs) are employed as both dispersant and stabilizer for nanowires. The three-dimensional architecture with functional groups on the periphery of HPMs enables the preparation of thixotropic HPMs-AgNW inks with solid contents of up to 20 wt.% in both aqueous and organ
