However, stick-slip banding is not equivalent for all solvents: stick-slip only becomes prominent at very low speeds for higher viscosity solvents. To distinguish the effect of viscosity from those due to differences in the evaporative flux, the velocities were normalized relative to the rate of evaporation of EtOH (Figure , Section S5). No obvious correlation can be seen between the corrected velocity values and the observed particle patterning supporting the conclusion that the change in stick-slip patterning results from viscosity. The most homogeneous films were produced for t-BuOH, having the highest viscosity. As viscosity is the resistance to motion in a fluid, intuitively, viscous forces should impact the depinning of the meniscus. It does appear to impact the particle patterning. Particle distribution should not be confused with total surface coverage, which can be studied quantitatively. The particle coverage was investigated for these films, as a function of speed and solvent. The observed increase in particle coverage with decreasing substrate withdrawal speeds is expected in the evaporative regime. The higher volatility of MeOH, compared with the other solvents, produced films that were much thicker at lower withdrawal speeds; these were often disordered multilayer films with variable thickness and gaps. When MeOH was used as the dispersant phase, all of the observed banded stick-slip structures at lower speeds were multilayer. All other films, for all of the other solvents, consisted of a single layer of particles of varying coverage fraction.
