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. Fried; 2nd Edition, 2003 See more We first calculate the entropy of mixing, the increase in the uncertainty about the locations of the molecules when they are interspersed.

Webgo beyond the one parameter Flory-Huggins theory. There is, however, no consensus on how to improve upon the Flory-Huggins theory. It is our view that our limited understanding of the thermo-dynamics of polymer blends is due to experimental as well as theoretical limitations. Miscibility in polymer systems is limited to the regime where < 2/N WebJan 15, 1996 · The Flory-Huggins interaction parameter K~,2 is often discussed as the measure of mutual solubility for solute-polymer systems. We have shown that the significant variations in second virial coefficient data possibly collected from different sources affect the final result, i.e. the physicochemical parameters which are used for discussion of ...
