Abstract
A stainless steel surface was treated with a glow discharge plasma. As a result of surface treatment, micro- and nanostructures were obtained. The surface roughness of the samples was increased. Thin fluoropolymer coatings were deposited on treated and untreated surfaces using the hot wire chemical vapor deposition (HWCVD) method. The structure of the obtained samples was studied by scanning and atomic force microscopy. Wetting properties were measured for all samples obtained. It has been shown that pretreatment of the surface before the deposition of fluoropolymer coatings makes it possible to increase the hydrophobicity of the final surfaces. Tests of coatings carried out using an ultrasonic cleaner have shown that plasma pretreatment before deposition and subsequent annealing after deposition make it possible to obtain stable coatings with stable hydrophobic properties.
