Flory-Huggins Theory - an overview ScienceDirect Topics

WebIn the absence of interactions, the typical size of the polymer grows as % aξ pN, as in Eq. (2.39). An important consequence of repulsion due to excluded volume is that the scaling of size is changed to R ∝ Nν, with an exponent ν>1/2. The variational treatment leading to Eq. (2.52) thus predicts the so-called Flory exponent of ν =3/5. WebA Flory-Huggins interaction parameter (χ₂₃') was earlier successfully used in the characterization of polymer blends. We propose to express the magnitude of modified filler/polymer interactions by using χ₂₃'. ...

However, in the Flory-Huggins approach we ignore this fact and account for the energy of mixing as if it is a mixture of ideal gases as before. This is analogous to the assumption of the dilute gas of monomers used in the Flory theory of real polymer chains.
