Webb14 apr. 2024 · Indeed, according to the classical Landau–Levich theory, the thickness of a film (h) produced by dip-coating on a flat substrate is related to the viscosity of the solution, dip-coating withdrawal speed, solution surface tension, and density [45,50,51]: WebbFurthermore, the dip-coating was carried out at different speed to verify if the film formation follows the theoretical prediction. The height of each film obtained at a different rate (using the first sample) was measured, and the results were compared with the theory using the Landau-Levich equation. lammin koneosa
