This video replaces a previous version which suffered from strange sound … 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 Meer weergeven The thermodynamic equation for the Gibbs energy change accompanying mixing at constant temperature and (external) pressure is A change, … Meer weergeven Polymers can separate out from the solvent, and do so in a characteristic way.
