Figure 4From: Spray-coated nanoscale conductive patterns based on in situ sintered silver nanoparticle inksMetallurgical microscope and SEM images of silver patterns and EDS analysis. Metallurgical microscope images of silver patterns: (a) inkjet-printed and (b) spray-coated patterns with 170°C post sintering and (c) spray-coated patterns with 170°C in situ sintering. SEM images of the morphology of spray-coated silver patterns based on 170°C post sintering (d) and in situ sintering (e) processes. (f, g) EDS analysis of the dark bulges and flattened area in (d, e), respectively.Back to article page
