| Abstract Scope |
In this paper, we reported a simple and effective solvothermal route to prepare copper and silver nanowire ring structures, demonstrating new possibility through hydrothermal/solvothermal route to prepare novel nanostructures. Single crystalline copper and sliver nanowire rings with wire diameters from tens to hundreds of nanometers and ring diameters around 15-40μm were synthesized through solvothermal process, in which cuprous chloride was used as copper resource and polyvinyl alcohol (PVA) used as reducing agent, and N-methyl-2-pyrrolidone (NMP) used to provide a water/NMP mixture reaction system was believed to be the key factor to form the novel closed structure. A growth-stress induced bending mechanism was suggested to explain the possible formation mechanism. The single crystallinity and perfectly closed structure of copper nanowire rings could potentially be explored for many interesting applications in the fields of nanoelectronics, nanophotonics and nanomechanics. Preliminary results on mechanical, optical and electrical characterizations of such nanostructures were also dicussed. |
