Self-assembly of amphiphilic graft copolymers
Amphiphilic copolymers are capable to self-assemble into nanoscale structures in solution and in bulk.1-4 These microstructures have attracted widespread interests in both fundamental and technological context, as they can be used in the field of delivery and release of drugs, agrochemisty, personal care and food products.5-7 With the development of new synthetic methods, the aggregation behavior of well-defined graft copolymers hasbecome a matter of interest owing to their sensitivity to the external chemical and physical stimuli such astemperature and pH.8 Regarding the diverse applications, it is important to control the shapes and sizes ofaggregate morphologies of graft copolymers by varying architectural parameters, amphiphilic property of backbone and so on. In the present work, using self-consistent field theory (SCFT) the microstructuresassembled by amphiphilic graft copolymers in melt and solution were studied. Furthermore, studies have also been carried out on the self-association of polypeptide based graft copolymers in selective solvent. Boththeoretical and experimental results show that the architecture parameters of the graft copolymers play an important role in determining the complex microstructure formation.
