Flory–huggins interaction
WebFlory-Huggins isotherm describes the degree of surface coverage characteristics of the adsorbate on the adsorbent [95]. The linear form of the Flory-Huggins equation is … 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).
