However, the polyelectrolyte complex phase should have a lower permittivity than pure water because of high polymer volume fraction, typically about ∼ 10%. This idea is further supported by Ref., where the authors used permittivity of ε r ≈ 30 to match their simulations with experiments. In contrast, the simulations in Ref. just used the permitivitty of water, however, their approach was aimed at the strong coupling regime, where the variation of perimitivitty does not have a strong effect on the phase behavior.
