Unique Toroidal Morphology from Composition and Sequence Control of Triblock Copolymers

摘要

Fundamental studies of the solution-state self-assembly of synthetic block copolymers have provided structural controls for the preparation of well-defined nanoscopic objects.With increased understanding of the principles that govern supramolecular assemblies,in both synthetic and natural materials,have also come numerous efforts and great prospects toward the development of such nanostructures as drug delivery vessels,magnetic materials,templates for biomineralization,and other functional materials.
