Abstract

This paper reports on the self-assembly of nanowires by the simple droplet evaporation of nanofluid (nanowires dispersed in liquid medium, e.g., water) on the superhydrophobic surfaces of systematically controlled microstructured patterns. The surface microstructure patterns (e.g., spacing) significantly affected the evaporation kinetics (e.g., contact angle and contact line dynamics) and wetting (e.g., transition from de-wetting to wetting state) of the nanofluid droplets, resulting in the unique self-assembly patterns of nanowires on the superhydrophobic surfaces (e.g., better assembly and alignment on denser microstructures).
