Webthese models, χ is replaced with an effective interaction parameter, χeff, to account for the interactions introduced by salt. In the simplest case χeff=χ0+mr (4) where χ0 is the Flory-Huggins parameter for the salt-free system, r is a suitable measure of salt concentration and m is a system-dependent proportionality constant. 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 …
