    • Note that ρ is a dimensionless quantity that does not make reference to the number of effective interaction centers, I N, used to discretize the chain contour. Therefore, it is an invariant of our coarse-grained model that would not change if we chose a different discretization and can be directly compared to experiments. By the same token, the coefficients of the nonbonded interaction free energy function, eq 2, are also invariants. For instance, the second-order term, vAA, is related to the segmental virial coefficient, V̄AA, via vAA, V̄AAN2, R3eo, that is, vAA is the Fixmann parameter that describes the strength of the excluded interaction

    • Usually, Flory-Huggins parameters can be calculated from the solubility parameters, and those parameters between polymers and solvent SB(MEK)are calculated using this method. However, Flory-Huggins parameters calculated this way cannot reflect hydrogen bond and electrostatic interaction, which are important in solvent SA(DMF, SC, and SDwater, Instead of considering these complicated interactions in a sophisticated model, for simplicity, some estimated Flory-Huggins parameters are adopted to reflect the solvent quality
