| Abstract Scope |
Reactive inkjet printing is a novel technique that involves selective deposition of precursor ink followed by synthesis of functional materials in film, unlike conventional inkjet printing that requires synthesis of nanoparticles prior to ink formulation. The technique offers advantages such as improved ink stability, film cohesion, and electronic performance. Furthermore, several opportunities arise from this technique, including area-selective morphological control, tunable properties, and gradient multi material blending. In this study, the choice of solvent for metal-organic complex zinc oxide precursor inks is investigated, taking into consideration reaction conditions, size effects, mass transport, and compatibility with reactive inkjet printing, and applicability to energy harvesting, sensing, and photonics. We propose a simple, optimized multi-solvent zinc oxide precursor ink formulation based on evaluation using computational fluid dynamic models and experimental evaluation. |
