Flory-huggins theory derivation
WebHence, in our application of the Flory–Huggins theory to food materials the interaction parameter has lost its fundamental meaning. The Flory–Huggins theory is best introduced for a polymer solution. The polymer volume fraction is denoted by ϕ p = 1 − ϕ w, and N p is the ratio of the molar volumes of the polymer monomer and the solvent ... Webto polymers, using the same machinery. The lattice theory of polymer solutions is known as Flory-Huggins theory. In many ways, you will find this theory similar to the small-solute case, except that the statistics are a little more complicated given that a polymer is a connected entity. Figure 1 shows a lattice model of a polymer.
