제목 Direct Modification of Block Copolymer Micelles by Surface-Initiated Polymerization
초록 Surface characteristics of a block copolymer micelle can be tuned by employing a block copolymer having the corona-forming block with a desired functionality. However, it cannot be guaranteed that the micelle structure of a newly synthesized block copolymer is the same as that of the unmodified one. In this presentation, we demonstrate the direct modification of the corona part in a block copolymer micelle by surface-initiated polymerization. We first synthesized block copolymers having a chain transfer agent positioned at the end of the corona block and assembled them into a spherical micelle. Then, in situ polymerization was conducted directly on the surface of the micelles, which resulted in the selective modification of the corona part while maintaining the micelle structure. In addition, we investigated the effect of surface modification of the micelle on the micelle solubility by varying functional monomers incorporated in the surface-initiated polymerization.
