Abstract
One-dimensional silver nanomaterials, nanorods, and nanowires (NWs) were achieved by a solution-phase method. The geometry of the silver nanostructures was successfully tuned by adding polyvinylpyrrolidone (PVP) of different molecular weights. A possible mechanism, involving the suppression effect from PVP on the growth rates at different crystal facets, is used to explain the PVP-dependent morphology of the Ag nanowires achieved in this experiment. To evaluate its potential application in transparent electrodes, we also investigated the electrical conductance and optical transmittance after NWs were transferred to transparent polyethylene terephthalate substrates. Our findings indicated a possible and simple approach to control the morphology and then the functional properties of nanostructured silvers.
