The influence of post-annealing treatment on the wettability of Ag+/Na+ ion-exchanged soda-lime glasses

► Ion exchanged Ag+/Na+ soda lime glasses were annealed in different temperatures and times. ► Silver oxide nano-patterned layers were formed on the surfaces, which changed their wettability from hydrophilic to hydrophobic. ► The best condition for attaining the most hydrophobic surface was deduced. ► Contact angle changes were explained due to the surface roughness and the area fraction of the coated layers.
