Flory-huggins fh theory
WebThe Flory-Huggins interaction parameter χ gives a measure of the interaction of the polymer chains with the solvent molecules as well as the polymer-polymer interaction. To understand the meaning of χ, one must consider the free energy of mixing of pure polymer with pure solvent as considered by Flory and Huggins theory. WebWe have demonstrated the applicability of the Flory-Huggins (FH) theory to describe the thermodynamics of polycarboxylic acids solutions. Moreover, for citric acid we can …
