Nanocomposites from Natural Materials as Hydrophobic Photocatalytic Coatings N2 - This study reports on the synthesis, characterization of polystyrene (PS)/CuO-Fe?O? nanocomposites, and their application as hydrophobic coatings. CuO and Fe?O? materials were synthesized from natural materials by the milling method. Meanwhile, the PS/CuO-Fe?O? nanocomposites were synthesized by the sol-gel method. Furthermore, the hydrophobic coating on the glass substrate was made by spin-coating. To obtain the highest value of contact angle, the composition of both CuO and Fe?O? in nanocomposite as well as calcination temperatures were varied. Sample characterization was conducted using XRD, SEM, and UV-Vis spectrophotometry. The sessile drop method was used to determine the contact angle. Results showed that PS/CuO-Fe?O? nanocomposite was successfully obtained with a crystal size between 40?52 nm and grain size of 92 nm. The highest contact angle was 125.46° at 3:1 composition and calcination temperature of 200 °C. The composite was hydrophobic, but photocatalyst activity was very small at 0.24%.
