Flory - huggins
WebThe Flory-Huggins theory is widely used still and has been successful, largely, in describing thermodynamics of polymer solution s. There are a number of limitations to the original formulation. The main ones are (Fried, 2003) Applicability only to solutions that are sufficiently concentrated that they have WebHere the molecule types A, B have an enthalpic interaction between them characterized by the Flory-Huggins parameter $\chi$, and the component C only appears in the entropy of mixing -term. On that note, the present free energy can be obtained by a three state (Potts) Ising model via the Bragg-Williams mean field approximation.
