A theoretical model developed predicts the thickness of a polymer film, coated on a rotating and translating cylindrical support. A model for the deposition process can be used to determine optimal operating conditions. It was validated experimentally and shows that the film-thickness morphology is quite sensitive to certain operating parameters. For example, particular sets of operating parameter values can produce highly nonuniform film thicknesses. Selected examples of the model calculations are discussed, as well as their implications.
