Title: Low Density Gold Nanowire Aerogels: Synthetic Control through Ligand Exchange

Abstract

Gold nanowire aerogels have been formed through freeze casting aqueous suspensions of high quality gold nanowires (AuNW). Since the properties of the final aerogel are highly dependent upon the freeze casting conditions, moving from aqueous to organic suspensions would open a new parameter space for optimization of aerogel properties and processing conditions. In this study, the surface chemistry of gold nanowires was modified through ligand exchange in order to improve their colloidal stability in nonpolar organic solvents.
