Improvements in the electroless deposition of Ag nanowires in hot ethylene glycol for resistive touchscreen device

We report several approaches to improve the quality of silver (Ag) nanowires synthesized by electroless deposition in hot ethylene glycol (polyol). Ultralong Ag nanowires with lengths up to 50 μm and about 60 nm in mean diameter were prepared using CuCl2 as stabilizer. Without CuCl2, mostly large Ag particles were produced due to oxidative etching of multiply-twinned Ag seeds. Sonication of the AgNO3/EG solution prior to injection resulted in...
