WebMay 20, 2024 · Polymer-solvent interaction is a fundamentally important concept routinely described by the Flory-Huggins interaction (χ), Hildebrand solubility( δ) and the relative energy difference (RED) determined from Hansen solubility in experimental, theoretical and simulation studies. Here we performed a machine learning study based on a … In the most general case the interaction and the ensuing mixing parameter, , is a free energy parameter, thus including an entropic component. [1] [2] This means that aside to the regular mixing entropy there is another entropic contribution from the interaction between solvent and monomer. See more 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. … See more We first calculate the entropy of mixing, the increase in the uncertainty about the locations of the molecules when they are interspersed. In the … See more Flory-Huggins theory tends to agree well with experiments in the semi-dilute concentration regime and can be used to fit data for even more complicated blends with higher … See more 1. ^ "Thermodynamics of High Polymer Solutions," Paul J. Flory Journal of Chemical Physics, August 1941, Volume 9, Issue 8, p. 660 Abstract. Flory suggested that Huggins' name ought to be first since he had published several months earlier: … See more The thermodynamic equation for the Gibbs energy change accompanying mixing at constant temperature and (external) pressure is See more Polymers can separate out from the solvent, and do so in a characteristic way.
