A hybrid material of polystyrene (PS)–ZrO2 was developed by the sol–gel technique and deposited spin-coating on AM60 AM60–AlN nanocomposite surfaces to enhance corrosion resistance in marine environments. PS–ZrO2 with an average thickness ≈305 ± 20 nm dispersed homogeneously, presenting isolated micro–nano-structure defects air trapped inside, which led increase roughness (≈4 times). The wettab...
