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. WebThe scaling exponent ν is clearly dependent on the dimension of space: For d = 1, self-avoidance causes the walk to always move in one direction, yielding ν = 1, but as d → ∞ …
