Evaporation-driven ring and film deposition from colloidal droplets
Evaporation-driven ring and film deposition from colloidal droplets
Evaporating suspensions of colloidal particles lead to the formation of a variety of patterns, ranging from a left-over ring of a dried coffee drop to uniformly distributed solid pigments left behind wet paint. To characterize the transition between rings and uniform deposits, we investigate the dynamics of a drying droplet …
