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

Photos of as-synthesized solutions after two months for the addition of 3 wt% KCl and (b) without KCl. (c) Schematic for the effect of KCl on the wire formation, which can be grouped into two roles: (i) the binding of KCl on the (100) plane that results in the passivation of the plane and (ii) the formation of AgCl and release of Ag⁺-cations that are reduced to Ag⁰-atoms by EG. The latter effect limits the supply of Ag⁰-atoms and hence the growth of the NWs.
