Abstract

Block copolymers have attracted extensive attention because they can self-assemble into various nano-sized structures. However, the hybrid structures self-assembled from AB-type block copolymers are very limited, wherein the same chemical composition can self-assemble into different geometric structures. Inspired by the theoretical prediction that A₁B₁A₂B₂ tetrablock copolymer can self-assemble into lamella-sphere (LS) structure, the A₁B₁A₂(B₂)_m (m = 1, 2) copolymer was proposed to facilitate the formation of hybrid lamella-cylinder (LC) nanostructure in this paper. Through the calculation of self-consistent field theory, it has been demonstrated that A₁B₁A₂(B₂)₂ is capable of self-assembly into hybrid LC structure, while the A₁B₁A₂B₂ does not exhibit the ability to form such structures.

期刊介绍： Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage. Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
