Development of Industrial Purification Methods for Silver Nanowires Used as Transparent Conductive Materials

Silver nanowires hold significant potential for transparent conductive films, particularly in smartphone touch panels. However, spherical particles and short nanowires in freshly synthesized silver nanowires necessitate an effective purification process to enhance their transparent conductive properties. The authors have introduced a cross-flow method that enables cost-efficient, large-scale purification tailored for industrial applications.
