Flory–huggins interaction parameter χ
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. WebFeb 7, 2014 · The Flory–Huggins interaction parameter determined from scattering experiments, χ SC, was found to be a function of block copolymer composition, chain length, and temperature for both salt-free and salty systems.
