Flory theorem
WebFeb 1, 2024 · Flory theory provides a simple, unifying description for a wide range of branched systems, including isolated trees in good and θ-solvent, and tree melts. In particular, the approach provides a common framework for the description of randomly branched polymers with quenched connectivity and for randomly branch ing polymers … Webpects Flory theorem[8] to hold and the mean square sep-arations to scale as L1=2 as the short segments behave as a random walker. On the other hand, when the segments of equilibrium globule get larger, the nite size of the cu-bic lattice puts an upper limit on the possible values of R(L) and we expect its value to saturate. In contrast,

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 for mixing a polymer with a solvent. Although it makes simplifying assumptions, it generates useful results for interpreting exp… WebSep 24, 2007 · The generalization of the Flory theorem for structurally asymmetric mixtures was derived and tested by direct visualization of conformational transformations of …
WebAug 4, 2024 · Here we use the fact that the Flory theorem, originally derived for chains in a dense polymer melt, holds also for chain fragments within the core of globular proteins, if the average over buried fragments collected from different non-redundant native structures is considered.
