Flory-huggins理論
Did you know?
Webn (1) A thermodynamic theory of polymer solutions, first formulated independently by Flory and Huggins, in which the thermodynamic quantities of the solution are derived from a simple concept of combinational entropy of mixing and a reduced Gibbs energy parameter, the “χ parameter” (a dimensionless quantity). The Flory-Huggins theory lead to the … WebFlory–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 …
WebFlory-Huggins solution theory offers a simple but powerful mathematical model of the thermodynamics of polymer blends. This model expounds on regular solution theory, by taking into account the dissimilarities between lengths of polymer chains. FH theory is derived by a simple lattice model, constraining each monomer onto a distinct lattice ... Webchain ends). 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 …
WebTo handle such a complicated simulation, the Flory-Huggins interaction parameters were obtained from molecular dynamics simulation and enabled to scale the segregation … WebThe applicability of Flory-Huggins, mainly for biochemical applications, is discussed in Chan and Dill (1997). They find that Flory-Huggins is more applicable for articulate …
