AI Technical Summary
Current transparent conductive films, primarily made of indium tin oxide (ITO), are inflexible and rely on indium, a rare and non-renewably sourced material, limiting their application in flexible devices and posing environmental concerns.
Development of stable, transparent, and conductive ink formulations based on silver nanowires, suitable for additive manufacturing by screen printing, which replace ITO by using a combination of silver nanowires, monohydric alcohols, hydroxy propyl methylcellulose, ethylene glycol, and propylene glycol propyl ether, optimizing viscosity and composition to prevent foam formation and enhance conductivity.
The silver nanowire ink provides flexible, conductive, and transparent electrodes with improved manufacturing costs and reduced environmental impact, suitable for various applications including 5G smartphones, wearables, and organic photovoltaics, while avoiding the limitations of ITO.
