Simulation of conductivity of polymer films on metal surface

Studying the Self-Organization of Macromolecules on the Surface of Textured Polymer Coating of Metal Sheet

“…Thus, the cost of production is reduced and it satisfies the quality requirements for polymer coating thickness [4]. However, an excessive decrease in the coating density leads to reduced corrosion resistance [5]. Therefore, the development of simple methods that allow determining the deviation of the polymer coating density from the standard one is a relevant task.…”

“…The texture of these coatings is created due to the presence of the filler consisting of polyacryl or polyamide granules in the paint material. During the drying process, polymer molecules are adsorbed on the particles surface, forming associates of the radial "viscous fingers" type [5], which are collected in star-shaped clusters scattered over the entire surface of the metal sheet (Figure 1). The surface morphology of such coatings depends on their formation regime and chemical structure of the paint material.…”
