Abstract
A method of room temperature synthesis of magnetic metal oxide nanoclusters within a diblock copolymer matrix includes the step of synthesizing, by ring opening metathesis polymerization technique, a diblock copolymer having a repeat unit ratio m/n, introducing, at room temperature, one or several metal containing precursors into the one block of the diblock copolymer, and processing the metal containing diblock copolymer by wet chemical technique to form nanoclusters of the metal(s) oxide within the diblock copolymer matrix. Specific reaction for synthesis of CoFeOand CoOnanoclusters within diblock copolymers, such as [NOR]/[NORCOOH]and [NOR]/[CO(bTAN)], respectively is used in the method of the present invention.
