High-Yield Synthesis of Uniform Ag Nanowires with High Aspect Ratios by Introducing the Long-Chain PVP in an Improved Polyol Process
Table 1
Products obtained by using PVP with different MWs. (
°C and
). Note that
D and
L mean the average diameter and length of Ag nanowires, respectively.
| No | PVP | Final product (yields) and size of nanowires |
| (1) | K17 (MW = 15000) | Nanoparticles (~60%) and nanowires (~40%); D: ~120 nm, L: ~3 μm | (2) | K25 (MW = 38000) | Nanoparticles (~50%) and nanowires (~50%); D: ~100 nm, L: ~3 μm | (3) | K30 (MW = 58000) | Nanoparticles (~10%) and nanowires (90%); D: ~180 nm, L: ~8 μm | (4) | K60 (MW = 200000) | Nanoparticles (~5%) and nanowires (~95%); D: ~120 nm, L: ~8 μm | (5) | K90 (MW = 800000) | Nanowires (~99%); D: ~100 nm, L: ~10 μm |
