Abstract
The present invention provides a method for analyzing diffusion coefficients of solvent molecules in polymer materials by applying a diffusion coefficient analysis model using 4 descriptors related to solvent properties. The present invention can provide optimum solvents when it is necessary to screen solvents suitable for drying procedure in the preparation of polymer films using a solvent process or it is necessary to analyze the permeability of polymer materials used in the final products by effectively analyzing the diffusion coefficients of solvent molecules.
