Abstract
- Based on the fact that block copolymers can self-assemble to form many ordered structures under soft confinement conditions, they are widely used in catalysis, electronic devices, optical sensing and other fields. At present, only the self-assembly morphology of linear triblock copolymers under soft confinement has been analyzed. There is no unified conclusion on the self-assembly behavior of copolymers under soft confinement. Based on this background, this paper focuses on studying the morphology of triblock copolymer particles under soft confinement. A phase diagram is constructed by tuning the volume fractions of the three blocks (fA, fB, and fC). Our simulations predicted various unique self-assembled nanostructures, including lamella + sphere, cylinder, perforated layer, lamella + cylinder, core-shell patch. By changing the selectivity between the block and the solvent, the morphology transition of the copolymer with the chain length ratio of 1:x:1 was predicted. The morphology transition mechanism was verified by calculating the ratio of <DEE²> to the average length (L), the average bond length of B block chains, and their contact number.
