Abstract Nanocomposite coatings based on polyvinylidene fluoride (PVDF) and carbon nanoparticles (nano‐carbon) were prepared via spraying. The influence of nano‐carbon loading has been examined; however, the preparation method notably affects properties coatings. A diverse array hydrophobic antibacterial was successfully achieved by employing PVDF/nano‐carbon system through either a one‐step or two‐step approach. In approach, PVDF mixed applied together. contrast, first entails applying sublayer, followed deposition layer. process results in single‐layer coating, while yields dual‐layer coating system. approach significantly improved hydrophobicity due to notable aggregation within surface true superhydrophobic property (WCA = 157° SA ~ 2°) using 20% at drying temperature 200°C. bacterial adhesion study indicated varying efficacy among coatings, with achieving highest rate 99.3%. Implementing this strategy healthcare food‐contact applications can substantially reduce contamination risks. Highlights degrees fabricated. High‐temperature used fabricate more stable led higher than method. Superhydrophobicity key high rates (99.3%). localization governed coatings' performance.
