Abstract Summary: A novel way to prepare polymer hair/polysilsesquioxane core hybrid nanospheres is presented based on a self‐assembly and gelation process of a reactive block copolymer, poly(ethylene oxide)‐ block ‐poly[3‐(trimethoxysilyl)propyl methacrylate] (PEO 113 ‐ b ‐PTMSPMA 206 ). Nanospheres of uniform size were obtained. Transmission electron microscopy (TEM), dynamic light scattering (DLS), and static light scattering (SLS) were employed to characterize the products.Schematic of the PEO‐ b ‐PTMSPMA nanospheres formed here, the light gray part represents the PEO hairs, the dark parts are the polysilsesquioxane from the gelation of the PTMSPMA blocks of the self‐assembled sphere.
