Program Asymmetric Binary Packing Lattices of AB1CB2 Tetrablock Terpolymers
ABC-type block terpolymers have great potential to self-assemble into rich ordered nanostructures, e.g., binary cylindrical structures. Recent experiments observed novel binary cylindrical structures in AB1CB2 linear tetrablock terpolymers, which have a high coordination number of A cylinder (CNA = 8). To elucidate the formation mechanism of high-CNA binary cylindrical phases and thus to stabilize more high-CNA phases, we investigate the self-assembly of AB1CB2 block copolymers, focusing on the exploration of distinct high-CNA cylindrical phases. We introduce a polygonal tiling approach to divide the planar space into different regions for two B blocks to fill through local separation. Based on this approach, the transition mechanism between different binary phases is clarified. Following the transition mechanism, we predict a multitude of high-CNA binary cylindrical phases by tailoring the key architectural parameters such as the volume fraction or the conformational parameter of the A block, including those with CNA = 6, 7, 8, 9, 10, and 12. Our theoretical prediction of so many novel binary cylindrical phases is expected to promote further experimental studies on the self-assembly of ABC-type block copolymers.
期刊介绍：
Macromolecules publishes original, fundamental, and impactful research on all aspects of polymer science. Topics of interest include synthesis (e.g., controlled polymerizations, polymerization catalysis, post polymerization modification, new monomer structures and polymer architectures, and polymerization mechanisms/kinetics analysis); phase behavior, thermodynamics, dynamic, and ordering/disordering phenomena (e.g., self-assembly, gelation, crystallization, solution/melt/solid-state characteristics); structure and properties (e.g., mechanical and rheological properties, surface/interfacial characteristics, electronic and transport properties); new state of the art characterization (e.g., spectroscopy, scattering, microscopy, rheology), simulation (e.g., Monte Carlo, molecular dynamics, multi-scale/coarse-grained modeling), and theoretical methods. Renewable/sustainable polymers, polymer networks, responsive polymers, electro-, magneto- and opto-active macromolecules, inorganic polymers, charge-transporting polymers (ion-containing, semiconducting, and conducting), nanostructured polymers, and polymer composites are also of interest. Typical papers published in Macromolecules showcase important and innovative concepts, experimental methods/observations, and theoretical/computational approaches that demonstrate a fundamental advance in the understanding of polymers.
