Outline of Final Research Achievements

We report that the systematic synthesis of gold nanowires (AuNWs), the kinetic control of their growth, and their rheological investigation were demonstrated. From the structural analysis, it was found that the length of AuNWs varies from nanometer to micrometer order and the structural parameters of AuNWs during their growth were successfully obtained. When the contour length of AuNWs increased to micrometer order, the AuNWs solution showed rheological behavior which was found to be responsible for entanglement between AuNWs. This study addresses the fundamental issue of how the mechanical properties of AuNWs are related to their morphology using new approaches such as static light scattering and rheological measurements.
