Polymer–Solvent Interaction Parameter χ

A novel insight into membrane fouling mechanism regarding gel layer filtration: Flory-Huggins based filtration mechanism

“…For many systems, χ has been found to increase with polymer concentration and decrease with temperature with a dependence that is approximately linear with, but in general not proportional to, 1/T. Whereas, χ is generally insensitive to the molecular weight of the polymer, except for systems with low molecular weight polymers 33 . χ value can be commonly determined by measurements on dilute solutions, especially osmotic pressure measurements.…”

“…χ value can be commonly determined by measurements on dilute solutions, especially osmotic pressure measurements. Meanwhile, data of this parameter for lots of polymer-water systems can refer to literature 33 .…”

Understanding the correlation and balance between the miscibility and optoelectronic properties of polymer–fullerene solar cells

“…It has been reported that the dimensionless Flory-Huggins interaction parameter (x 12 ) can be used for evaluating the miscibility between polymers and small molecules. 77,78 As already described in previous publications, the interaction parameters can be determined as follows: 77,78 Fig . 5 Schematic of the morphological evolution of polymer-fullerene with (a) poor miscibility and (b) good miscibility.…”

Structural evolution of a constrained epoxy functional polyethylene network crosslinked by a bio-based reactant

“…(8). The Flory-Huggins parameter between xylene and Et-co-GMA used was 0.4 [47]. This value was chosen by assuming the copolymer as a LDPE.…”
