Ultrathin gold nanowires (AuNWs) have shown great potential toward applications in flexible electronics. However, they suffer from high surface instability that consequently limits their applicability for solution-processed composite materials. To overcome this limitation, we show for the first time how a synthetic thiolated small-molecule ligand such as ethyl 11-(4-mercaptobenzamido) undecanoate can stabilize the AuNW surface enabling their manipulation in solution-processed composite manufacturing techniques. As a proof of concept, we show how such stabilized NWs can be formulated into a PDMS matrix and spin-coated to afford stretchable elastomeric strips capable of sensing mechanical deformation with loading as low as 0.03 wt %.

Abstract

Ultrathin gold nanowires (AuNWs) have shown great potential toward applications in flexible electronics. However, they suffer from high surface instability that consequently limits their applicability for solution-processed composite materials. To overcome this limitation, we show for the first time how a synthetic thiolated small-molecule ligand such as ethyl 11-(4-mercaptobenzamido) undecanoate can stabilize the AuNW surface enabling their manipulation in solution-processed composite manufacturing techniques. As a proof of concept, we show how such stabilized NWs can be formulated into a PDMS matrix and spin-coated to afford stretchable elastomeric strips capable of sensing mechanical deformation with loading as low as 0.03 wt %.
