In this study, the Flory–Huggins interaction parame-ter (χ 12) between PVdF and solvent is estimated ... WebFinally, a Flory-Huggins-type interaction is introduced for the nonideal (interchain) interactions: where IJ(jr - r′j) is a mean-field energetic interaction between beads of type I at r and type J at r′. The mean-field intrinsic chemical potentials can easily be derived by functional differentiation of the free energy: íI(r)) äF/äFI(r).
