Controlled Synthesis of Hollow TiO2 Nanospheres Templated by Polymeric Micelle with Core-Shell-Corona Architecture
Hollow TiO2 nanospheres have been successfully prepared by templating the polymericmicelles of poly (styrene-b-[3-(methacryloylamino)propyl] trimethylammonium chloride- b-ethylene oxide) (PS-b-PMAPTAC-b-PEO), which shows a core-shell-corona structure in aqueous solutions. It was found that, in such system, the wall thickness of the hollow TiO2 is fine tuned by varying the concentration of the TiO2 precursor.
