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. In the … See more Flory-Huggins theory tends to agree well with experiments in the semi-dilute concentration regime and can be used to fit data for even more complicated blends with higher … See more 1. ^ "Thermodynamics of High Polymer Solutions," Paul J.
