High Mechanical and Tribological Stability of an Elastic Ultrathin Overcoating Layer for Flexible Silver Nanowire Films

A novel, nanoscale, thickness-controlled, elastic graphene oxide-polydiallyldimethylammonium chloride (GO-PDDA) film using a layer-by-layer technique on silver nanowires and a flexible substrate is reported. Micro- and nanoscale wear and flexibility depending on the thickness and/or elastic nature of the overcoating layer demonstrate high mechanical stability with the PDDA inserted overcoating layer.
