Constructing patches on colloidal nanoparticles is one of the effective strategies for producing anisotropic building blocks for superstructures. Patch formation on colloidal particles was typically induced in their solutions. We also reported formation of patchy micelles from spherical micelles of diblock copolymers in a solution. In this presentation, we demonstrate the formation of multiple patches on diblock copolymer micelles coated on a solid substrate. For patch formation, spherical micelles after crosslinking their cores were first coated on a substrate and then exposed to a core-preferable solvent. The number of patches on the micelles depending on the block ratio of copolymers was characterized by SEM and AFM. We also investigated the confinement effect on the patch formation by restraining spherical micelles in localized spaces.
