Comprehensive Synthesis Study of Well-Dispersed and Solution-Processed Metal Nanowires for Transparent Heaters

Figure 4

SEM images recorded for a AgNO₃ : PVP weight ratio of (a) 1 : 3, (b) 1 : 6 and (c) 1 : 9. (d) Mean length and mean diameter as a function of the AgNO₃ : PVP weight ratio. The inset shows the corresponding aspect ratio as a function of the AgNO₃ : PVP weight ratio. (e) Schematic drawing for the wire formation. (111) and (100) label the planes, where the wire formation and passivation occur. Grey spheres indicate silver atoms, whereas red, black, blue, and white spheres indicate oxygen, carbon, nitrogen, and hydrogen atoms from the PVP molecule, respectively. The scale bar in (c) also applies to (a) and (b).
