Flory–huggins interaction
WebA Flory-Huggins interaction parameter (χ₂₃') was earlier successfully used in the characterization of polymer blends. We propose to express the magnitude of modified filler/polymer interactions by using χ₂₃'. It was calculated from retention data of test solutes during an inverse gas chromatography (IGC) experiment. IGC is an ... WebSep 14, 2024 · The Flory-Huggins interaction parameter $$\\chi$$ χ for polymer-solvent mixtures captures the nature of interactions and provides insights on solubility. …
