Extended asymptotic solutions to the spin-coating model with small evaporation

摘要

We obtain improved asymptotic solutions to the spin-coating with small evaporation model. In particular, the spinning of a solute-free fluid, and a two-component solvent–solute solution are studied. In addition, the non-negligible effect of the rise of solute concentration on the solution viscosity at the end of the spin-coating process is considered.
