Flory huggins interaction parameter table
WebThe Flory-Huggins interaction parameter χ - as used today - is for solutions of homopolymers in low molecular weight liquids defined in the following way, where p 1 and p 1, o are the vapor pressure of the solvent … 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 …
