  • Patent number: 12018111
    Abstract: Proposed are a core-satellite micelle containing a tetra-block copolymer and a preparation method thereof. The core-satellite micelle includes a core, a shell surrounding the core, and a plurality of satellite domains positioned inside the shell. The core-satellite micelle contains a tetra-block copolymer represented by Structural Formula 1 below. The shell includes a first-monomer first block A1 and a first-monomer second block A2, and the satellite domain includes a second-monomer first block B1 and a second-monomer second block B2. The core-satellite micelle is foiled through self-assembly of the tetra-block copolymer, thereby having a larger interfacial contact area than existing block-copolymer micelles. Therefore, the core-satellite micelle can be used in next-generation nanotechnology applications such as drug delivery systems, porous catalyst materials, and sensors.
