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 …
WebApr 11, 2024 · A commonly adopted theoretical framework is the Flory-Huggins theory of phase separation (14, 15).
