摘要

The use of self-assembly to obtain well-ordered structures has attracted increasing interest due to the ease of accessing complex structures with small feature sizes. Block copolymers comprised of chemically distinct polymers covalently joined at one end self-assemble into well-defined, ordered arrays of nanoscopic domains ranging from spheres to cylinders to lamellae, depending on the volume fraction of the components. The absolute size of the domains is defined by the molecular weight of the copolymer and the strength of the segmental interactions between the blocks. Functionality can also be introduced in the copolymer chains, which opens pathways to multilength scale ordering and, consequently, hierarchical ordering.
