A unified model for drying glassy polymer coatings

In recently published work, a unified model for drying glass polymer coatings has been developed.
researchers studied solvents evaporated from the polymethyl acrylates/ethyl benzene system as a one-dimensional numerical moving boundary experiment, along with heat transfer and mass transfer. The model is based on reasonable unbalanced thermodynamic principles and considers the contribution of viscosity elasticity to diffusion in the later stages of drying

In addition, at the end of the drying experiment, the sol-gel transition is thought to explain the high solvent concentration away from the gas-liquid interface (dry surface). The Galerkin finite-meta method is used to solve model equations. The model prediction of drying speed and solvent concentration curve was found to be satisfactory with the available experimental data. This work can be implemented to design and optimize industrial processes.
