High-Yield Synthesis of Uniform Ag Nanowires with High Aspect Ratios by Introducing the Long-Chain PVP in an Improved Polyol Process
TEM images of the Ag nanoproducts using different MWs of PVP:(a) K30 (MW = 58000), (b) K60 (MW = 200000), and (c) K90 (MW = 800000). (d) A typical SAED of one Ag nanowire; the spots from superimposition of the  and  zone axis are indicated. (e) A typical HRTEM image of a selected area of an individual Ag nanowire. (f) The nanowire of sample no. 5 used for the SAED and HRTEM studies with the area marked with a white pane indicating where the HRTEM image was recorded.
