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.

Description

[0001] related application [0002] This application claims priority to U.S. Provisional Application No. 62 / 828,654, entitled "Purification of Conductive Nanostructures," filed April 3, 2019, the contents of which are hereby incorporated by reference refer to. technical field [0003] The present invention relates to the purification of metallic nanostructures. Background technique [0004] Transparent conductors include films that are optically transparent and electrically conductive. One of the important applications of silver nanowires (AgNWs) today is to form transparent conductor (TC) layers for electronic devices such as touch panels, photovoltaic cells, flat liquid crystal displays (LCDs), organic light-emitting diodes (OLED), wearable devices, etc. A variety of techniques have produced transparent conductors based on one or more conductive media such as conductive nanostructures. In general, conductive nanostructures form a conductive network through long-term in...
