ABSTRACT The synthesized cobalt oxide (CoO) nanosheets embedded within a polymer matrix hold significant potential for applications in sensors, organic electronics, catalysis, photovoltaics, and energy storage devices. Using facile efficient preparation technique, we combine an organometallic cobalt(II) precursor, polystyrene‐ block ‐polymethyl methacrylate (PS‐ b ‐PMMA) diblock copolymer (DBC), solvents to ensure complete dissolution of all components without inducing precipitation or micro‐phase separation the liquid phase. Through straightforward thermal annealing process, salt DBC thin films undergoes decomposition, resulting formation CoO with uniform dense distribution pattern matching morphology DBC. Fourier transform infrared spectroscopy (FTIR) confirms selective phase DBC, while x‐ray photoelectron (XPS) indicates conversion into CoO. CoO/DBC hybrid is characterized using atomic force microscopy (AFM), scanning electron (SEM), scattering techniques. This study demonstrates simple effective route prepare well‐defined arrangement metal clusters, achieving highly confined particle self‐assembly process compared alternative solution‐based methods.
