Abstract
AbstractThe phase and order behavior of charged asymmetric diblock‐copolymer melts is studied by using coarse‐grained molecular dynamics simulation. One of the blocks is made charged and other one is kept neutral, and the study systematically explores how the charged diblock‐coploymer responses as the charge fraction of the charged block is varied from 10% to 50%. When charge fraction increases, the study finds ordered transitions from interconnected cylinder‐like structures to lamellae, then to gyroid structures. It is also found that domain size of the obtained equilibrium morphology decreases slightly with the increase in charge fraction of the charged block.
