Flory-huggins fh theory
WebOriginally, the Flory–Huggins theory is developed to describe the thermodynamic interaction between the blends of synthetic polymers or synthetic polymer solutions. 40 Recently, ... The FH-theory predicts the experimental solubility data quite well for almost all temperatures, except for 20 degrees, which is probably due to experimental errors.
