WebApr 25, 2007 · Using coarse-grained DPD simulations, we study the morphology of AB diblock copolymer brushes in selective solvents which are good for the anchored A blocks … WebJan 30, 2024 · The mixed polymer brush adopts a layered structure owing to the difference in solvent-polymer interactions. Stronger shear force from the solvent flow leads to larger extension of polymer chains on the top layer (or PA chains). Such layering structure also causes different coupling between polymer conformational dynamics and fluid dynamics.
