Flory–Huggins solution theory is a lattice model of the thermodynamics of polymer solutions which takes account of the great dissimilarity in molecular sizes in adapting the usual expression for the entropy of mixing. The result is an equation for the Gibbs free energy change See more The thermodynamic equation for the Gibbs energy change accompanying mixing at constant temperature and (external) pressure is A change, denoted by See more Polymers can separate out from the solvent, and do so in a characteristic way. The Flory-Huggins free energy per unit volume, for a polymer with $${\displaystyle N}$$ monomers, can be written in a simple dimensionless form See more • "Conformations, Solutions and Molecular Weight" (book chapter), Chapter 3 of Book Title: Polymer Science and Technology; by Joel R.

Webchain ends). However, in the Flory-Huggins approach we ignore this fact and account for the energy of mixing as if it is a mixture of ideal gases as before. This is analogous to the assumption of the dilute gas of monomers used in the Flory theory of real polymer chains. Essentially, this will lead to the same derivation as we did in WebTemperature and Concentration Dependence of Interaction Parameter. Many thermodynamic properties of polymer solutions such as solubility / miscibility, swelling equilibria, and other properties that depend on the mixture composition can be expressed in terms of the polymer-solvent interaction parameter χ.This unitless quantity was first …
