WebSupporting: 1, Mentioning: 22 - In this letter, we describe the capillary sorting of particles by size based on dip coating. A substrate withdrawn from a liquid bath entrains a coating whose thickness depends on the withdrawal speed and the liquid properties. If the coating material contains particles, they will only be entrained when the viscous force pulling … WebAs a result, the capillary and drag forces exerted on the particles are comparable.[51] During the dip coating pro- cess, the speed of the substrate withdrawal determines the thickness of the coated film, with faster withdrawals …
