Considerations and restrictions on the theoretical validity of the linearized cloudpoint correlation

Morphology transition of asymmetric polyetherimide flat sheet membranes with different thickness by wet phase-inversion process

“…3. In order to simplify thermodynamic description from Flory-Huggins theory, LCC correlation is rationalized by Boom et al [8] and Kools et al [9] (shown in Eq. (1)).…”

“…The phase behavior of a ternary polymer solution can be determined by cloud point measurements. The LCC (linearized cloud point curve) correlation describes a linear relationship between the nonsolvent concentration relative to the polymer concentration and the solvent concentration relative to the polymer concentration at the condition of phase separation, which is shown as [8,9]:…”
