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 ZnCl2 precursor dopant and wet …
