The block copolymer (BCP) and BCP brushes have self-assembly properties, but the brushes are different from the BCP morphologies because one end of the chain is attached to the substrate. Compared to BCP, which is actively studied for its application in various nanotechnologies, BCP brushes has not active explored yet. In previous BCP studies, researcher used the Self-consistent field theory (SCFT) model to predict the morphologies, but in the BCP brush studies, SCFT have limitation of high molecular weight and high grafting densities. Hence, we conducted simulations with a coarse-grained model which overcome limitation of SCFT model. And we investigated BCP brush phase behaviors with wide range of parameter values, including the grafting density, segregation strength between the blocks, preference and preferential interactions between polymer blocks and the substrate. Our study will provide a guideline for experimentalists from BCP brushes. |
