Aggregation behaviors of AB-type brush-block-brush amphiphilic copolymers in aqueous media

The aggregation behaviors of AB-type brush-block-brush amphiphillic copolymers in aqueous media was analyzed using gel permeation chromatography . Synthesis of prototype amphiphillic copolymer was performed by alternating free-radical polymerization of binary macromonomers. It was observed that the AB-type brush was composed of a polymethylacrylate backbone with ester linked side chains. Hierarchial generation from small rods to large rods was observed in the self-assembly process of prototype copolymer brushes. The result shows that the trend of an aggregation behavior for Janustype copolymer was different from prototype copolymer brushes.
