The future electronic devices will be soft, flexible and even stretchable to be more human friendly in the form of wearable computers and gadgets. Transparent conductors are currently made from a sputtered film of indium tin oxide (ITO) due to its high transmittance (95In this context, we are planning to develop a highly reproducible method of homogeneous silver nanowire synthesis with further surface functionalization by ligand exchange of organic ligands to inorganic ligands. We believe that this ligand exchange of original NWs surface ligands (PVP) can provide better interwire charge transport as well as material stability. Next, this modified Ag NWs will be investigated both in film and solution. The recent progress consists of a modified polyol synthesis resulting in Ag NWs with average diameters of 30 nm and length up to 50 µm. High-performance transparent electrodes require thin diameter and high aspect ratio as two key structural traits that determine their film performance. References: 1.*Ye al., Adv.
