摘要: Block copolymers spontaneously self-assemble into nanostructured morphologies with industrially attractive properties; however, the relationships between polymer architecture and self-assembled morphology are difficult to tailor for increased conformational restrictions. Using Dissipative Particle Dynamics, of comb- star-shaped diblock was simulated as a function number arms, arm length, weight fraction, A-B incompatibility. As arms on star, or grafting points comb, from three four six, ability ordered restricted. The molecular bridging adjacent domains observed both copolymers, which found be enhanced increasing arms. This study illustrates that viable alternatives applications would benefit highly bridged nanostructural domains.
