CuO nanodiscs have been synthesized on a large scale by a facile solution‐based method using polymers as crystal growth modifiers. X‐ray powder diffraction (XRD), scanning electron microscopy (SEM) and high resolution transmission electron microscopy (HRTEM) were carried out to characterize the structures and morphologies of the obtained products. The effects of reaction temperature, concentrations of polyacrylamide (PAM) and reactants on the morphology and size of the product were studied. The results revealed that the CuO nanodisc had single‐crystal monoclinic structures, and grew along (002) and (110) planes. Experimental conditions had all influence on the shape and size of the final products, but polymer PAM played the key role in formation of the CuO nanodisc. A possible growth mechanism of the CuO nanostructures based on typical polymer‐crystal interactions in a mild aqueous solution was given. Polymer‐directed crystal growth may provide promising routes to rational synthesis of various ordered inorganic and inorganic‐organic hybrid materials with complex forms and structural specialization.
