Abstract

A method for improving the quality of a dip coated layer that is deposited by flowing a solution along a substrate in a gap between the substrate and a wall, including: (a) determining a yield stress, a viscosity, a density, and a surface tension of the solution, and selecting a wet thickness of the coated layer; (b) determining a coating speed based on the determined viscosity, the determined density, the determined surface tension of the solution, and the selected wet layer thickness; and (c) selecting a distance for the gap and calculating the shear stress of the solution in the gap based on the gap distance, wherein the shear stress is greater than the yield stress.
