WebNov 25, 2008 · (Color online) Flory exponent ν as a function of U 0, calculated for chains larger than N p > 20 for the measures of chain size given by R g, R e, R g y ′ and R g z ′. For U 0 = 0 the polymers are free chains, while as U 0 increases the chains are squashed in the y − z plane. This illustrates the transition from three-dimensional random ... Web1.

The generalized Flory exponent is verified by the MHS relation, with an exponent α = 0.33 which is distinct in comparison with that for 1D polymers (0.5 < α < 0.8),2 as a result of the dimensional constraint.
Webscaling 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. Going beyond the mean-field variational treatment is not trivial, and one of the triumphs of renormalization group theory is to find the exact value of ν =0.591 ... WebMay 1, 2024 · The value of ν = 3 / 5 for a polymer in a good solvent was first predicted by P.J. Flory by a free energy minimization of the excluded volume and entropic contributions [1]. (For this, ν is also known as the Flory exponent.) The method uses a mathematical framework which we first presented [27] and applied [28] in 2016.
