This study reports on the synthesis, characterization of polystyrene(PS)/CuO-Fe<sub>2</sub>O<sub>3</sub> nanocomposites, and their application as hydrophobic coatings. CuO and Fe<sub>2</sub>O<sub>3</sub> materials were synthesized from natural materials by the milling method. Meanwhile, the PS/CuO-Fe<sub>2</sub>O<sub>3</sub> nanocomposites were synthesized by the sol-gel method. Furthermore, the hydrophobic coating on the glass substrate was made by the spin-coating. To obtain highest value of contact angle, the composition of both CuO and Fe<sub>2</sub>O<sub>3</sub> in nanocomposite as well as calcination temperatures were varied. Sample characterization was conducted using X-ray diffraction (XRD), scanning electron microscopy (SEM), and ultraviolet visible (Uv-Vis) spectrophotometry analysis. The Sessile drop method was used to determine the contact angle of the layer.
