Flory-huggins interaction
http://modem.ucsd.edu/htjcadd/publications/paper/63.pdf WebIn this work, we investigated the phase behavior of melts of block-copolymers with one charged block by means of dissipative particle dynamics with explicit electrostatic interactions. We assumed that all the Flory–Huggins χ parameters were equal to 0. We showed that the charge- correlation attraction solely can cause microphase …

WebThis review describes different trials to model and predict drug payload in lipid and polymeric nanocarriers. It traces the evolution of the field from the earliest attempts when numerous solubility and Flory-Huggins models were applied, to the emergence of molecular dynamic simulations and docking studies, until the exciting practically successful era of artificial … 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 ...
