Flory-huggins interaction
WebJun 1, 2007 · When Eq. (10) was used to fit the data of Fig. 2 a value of χ u = 0.49 ± 0.01 was obtained. Therefore, this value could be assigned to Flory–Huggins interaction parameter for the uncured SBR/toluene system. In the case of sulfur cured SBR the resulting values of χ are dependent on the crosslink density of the rubber. These results … WebJan 31, 2024 · Furthermore, an approach is outlined to convert liquidus miscibility to an effective Flory–Huggins interaction parameter χ. Crucially, determination of temperature-dependent amorphous miscibility paves a way to rationally optimize the stability and mixing behaviors of PSCs at actual processing and operating temperatures.

WebFinally, a Flory-Huggins-type interaction is introduced for the nonideal (interchain) interactions: where IJ(jr - r′j) is a mean-field energetic interaction between beads of type I at r and type J at r′. The mean-field intrinsic chemical potentials can easily be derived by functional differentiation of the free energy: íI(r)) äF/äFI(r). WebThis review describes different trials to model and predict drug payload in lipid and polymeric nanocarriers.
