Dissipative particle dynamics study of solvent mediated transitions in pores decorated with tethered polymer brushes in the form of stripes
We study self-assembly of a binary mixture of components A and B confined in a slit-like pore with the walls modified by the stripes of tethered brushes made of beads of a sort A. The emphasis is on solvent mediated transitions between morphologies when the composition of the mixture varies. For cer...

| description | We study self-assembly of a binary mixture of components A and B confined in a slit-like pore with the walls modified by the stripes of tethered brushes made of beads of a sort A. The emphasis is on solvent mediated transitions between morphologies when the composition of the mixture varies. For certain limiting cases of the pore geometry we found that an effective reduction of the dimensionality may lead to a quasi one- and two-dimensional demixing. The change of the environment for the chains upon changing the composition of the mixture from polymer melt to a good solvent conditions provides explanation for the mechanism of development of several solvent mediated morphologies and, in some cases, for switching between them. We found solvent mediated lamellar, meander and in-lined cylinder phases. Quantitative analysis of morphology structure is performed considering brush overlap integrals and gyration tensor components.
Розглянуто процес самоформування фаз у порi iз стiнками декорованими полосками полiмерної щiтки (з мономерiв сорту А), яка заповнена бiнарною сумiшшю iз компонент А i В. Акцент зроблено на дослiдженнi ролi розчинника при фазових переходах спричинених змiною складу сумiшi. Знайдено граничнi випадки квазиодновимiрного та квазидвовимiрного незмiшування. Показано, що механiзм формування морфологiй (та, в деяких випадках, переключення мiж ними) при змiнi складу сумiшi полягає у змiнi локального середовища для ланцюжкiв полiмерних щiток. Знайдено сформованi за посередництва розчинника ламеларнi, меандро-подiбнi та порядковi цилiндричнi фази. Структури вивчено за допомогою аналiзу iнтегралiв перекриття щiток та величин компонент тензора гiрацiї.
