我们合成了新型的TiO 2/ZnO-磷酸盐（TP/ZP）和聚甲基氢硅氧烷（PMHS）为基础的双层疏水涂层与潜在的抗菌性能调整应用于钢铁基材。将拓扑数据分析的数学方法应用于表面粗糙度数据。润湿特性表明，两层涂层的样品具有稳定的疏水行为。通过摩擦学表征，我们比较了未涂覆的钢样品和涂覆有不同涂层材料的钢样品的摩擦行为。未涂覆的基材（范围从0.221至0.269）和双层疏水涂层（范围从0.234至0.273）的摩擦系数表明，涂层赋予基材疏水性质，而摩擦行为没有显著变化。我们观察到的润湿和摩擦行为和涂层样品的平均粗糙度之间的相关性。划痕表面的显微照片的分析揭示了关于涂层的耐久性和耐磨性的初步信息。
We synthesized novel TiO2/ZnO-phosphate (TP/ZP) and polymethyl hydrogen siloxane (PMHS)-based two-layer hydrophobic coatings with potential antimicrobial properties tuned for application on steel substrates. The mathematical method of topological data analysis was applied to surface roughness data. Wetting characterizations showed stable hydrophobic behavior of the two-layer coated samples. Through tribological characterization, we compared the friction behavior of uncoated steel samples and steel samples coated with different coating materials. The coefficient of friction of uncoated base materials (ranging from 0.221 to 0.269) and the two-layer hydrophobic coatings (ranging from 0.234 to 0.273) indicated that the coatings confer hydrophobic properties to the substrates without a notable change in the friction behavior. We observed the correlations between the wetting and friction behaviors and the average roughness of the coated samples. Analysis of the micrographs of the scratched surfaces revealed preliminary information about the durability and abrasion resistance of the coatings.
