Decorated phases in triblock copolymers: Zeroth‐ and first‐order analysis

Abstract We study a two‐dimensional inhibitory ternary system characterized by a free energy functional that combines an interface short‐range interaction energy promoting microdomain growth with a Coulomb‐type long‐range interaction energy that prevents microdomains from unlimited spreading. Here, we consider a scenario in which two species are dominant and one species is vanishingly small. In this scenario, two energy levels are …
