Facile synthesis of V-shaped copolymer brushes grafted onto the surface of graphene oxide via coupling reactions

摘要

Mid-functionalized ABC triblock copolymers with a short central B block were synthesized via the RAFT process, and further used as well-defined V-shaped copolymers to graft onto graphene oxide by coupling reactions. Binary mixed homopolymer brushes comprising two chemically distinct homopolymers covalently immobilized on a solid substrate are an intriguing class of surface-responsive materials.1 These materials have been intensively investigated due to their rich phase morphologies, variable responsive properties and potential applications in nanoscience and nanotechnique.
