WebThe applicability of Flory-Huggins, mainly for biochemical applications, is discussed in Chan and Dill (1997). They find that Flory-Huggins is more applicable for articulate molecules like crosses and Ls, and it is a reasonable approximation for flexible chains, while globular molecules are better treated in “classical models”.
