Controlled Inkjetting of a Conductive Pattern of Silver Nanoparticles Based on the Coffee-Ring Effect

Conductive patterns with line widths of 5–10 µm are successfully fabricated by utilizing the coffee‐ring effect in inkjet printing, resulting in transmittance values of up to 91.2% in the visible to near‐infrared region. This non‐lithographic approach broadens the range of fabrication procedures that can be used to create various nanoparticle‐based microstructures and electronic devices.
