Abstract
The formation of self-assembled ZnO nanoclusters using diblock copolymers, is reported. The diblock copolymers, consisting of a majority polymer (norbornene) and a minority polymer (norbornene-dicarboxcylic acid), were synthesized with a block repeat unit ratio of 400/50, to obtain spherical microphase separation and hence a spherical morphology for the metal oxide nanoclusters. The self-assembly of the inorganic nanoparticles was achieved at room temperature in the liquid phase, using ZnCl 2 precursor dopant and wet chemical processing compatible with semiconductor manufacturing to convert to ZnO. FTIR and XPS spectroscopy, confirmed the association of the ZnCl 2 precursor with the minority block and the formation of ZnO, while TEM showed the spherical morphology of ZnO nanoparticles as targeted, and a relatively narrow size distribution ranging between 7 and 15 nm.
