The theory is formulated in terms of the volume fraction, tj), of monomers in the lattice (and 1 - solvent molecules in the lattice) and the Flory-Huggins f-parameter, which characterizes the energy of ...

The rank order miscibility of MFA in … WebJan 1, 2014 · The Flory–Huggins equation was derived by Flory [ 7] and Huggins [ 8] independently, for the case of polymer–solvent mixtures, and then generalized to include polymer blends by Scott [ 9 ]. The focus of this theory is the use of the previously described development of Δ S m and Δ H m into a central expression for Δ G m. 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.
