ХАРАКТЕРИСТИКА ВОДОВІДШТОВХУВАЛЬНИХ ТЕКСТУР, ОТРИМАНИХ НА ПОЛІМЕРНИХ ПЛІВКАХ ЗА МЕТОДОМ ОУЕНСА-ВЕНДТА

This research focuses on the characterization of liquid-repellent polymer films with micro- and nanostructured surfaces, using the Owens-Wendt method. The study investigates polydimethylsiloxane (PDMS) and low-density polyethylene (LDPE) films engineered to enhance water repellency. The Owens-Wendt approach was applied to estimate surface energy and evaluate the influence of surface texture on wetting behavior. Results demonstrated that while both materials exhibited superhydrophobic properties under specific conditions, PDMS surfaces showed lower stability against wetting transition compared to LDPE. The presence of the Cassie-Baxter state was confirmed through deviations from linearity in Owens-Wendt plots. These findings support the potential of structured polymer surfaces for developing efficient liquid-repellent materials in various applications.
