Conductive nanostructure purification

Abstract

A method of purifying a metal nanostructure composition containing desired nanostructures and undesired nanostructures. The method includes providing a solution within which metal nanostructures have been synthesized including desired and undesired nanostructures. The solution includes polyol and has a viscosity. The method includes diluting the solution with a dilutant to lower the viscosity of the solution and provide a diluted solution. The method includes sedimenting the undesired nanostructures from the diluted solution. The method includes collecting the supernatant with the desired nanostructures and retaining the undesired nanostructures inside the sedimentation device. In an example, such is via a sedimentation device, which is a special tray system designed with grooved bottoms to retain the undesired nanostructures.
