Copper‐Based Conductive Nanoinks: Scalable Synthesis via Continuous‐Flow Microwave‐Assisted Polyol Process

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Microwave‐assisted polyol synthesis in continuous flow produces metallic Cu nanoparticles, using ethylene glycol as solvent and reducing agent, lignin to stabilize the colloid and prevent oxidation, and metal‐seeds for particle size control. Metallic copper nanoparticles are a promising alternative to gold and silver in printed electronics due to their
