Electrochemical formation of polyacrylamide-sulfur composite coatings on titanium surfaces

Abstract

In this study, titanium was chosen as the substrate material to form composite coatings that replace traditional metal sheets. Colloidal nanoparticles, which are heterogeneous in nature, exhibit variations in size, shape, and composition that significantly affect their catalytic behavior.

These variations are crucial for understanding the interactions between individual particles, as they can alter the efficiency and performance of the coating. The role of electrolysis in controlling the deposition and stability of nanoparticles on titanium surfaces is also examined.

Sulfur wastes can be recycled into functionally active products by using polyacrylamide, a flocculating agent derived from indigenous polymers. This approach aims to expand the potential applications and improve the performance of these materials under practical conditions. Therefore, research in this area is of great importance, focusing on innovative methods for converting sulfur wastes into valuable bioactive compounds.

This research focuses on the formation of a composite material based on polyacrylamide and sulfur on the surface of a titanium plate through electrolysis. The study employed scanning electron microscopy (SEM) to analyze the resulting composite material. The findings revealed that the amide groups (–CONH₂) in polyacrylamide interact effectively with sulfur, enhancing the adhesion and stability of the deposited sulfur layer. Additionally, polyacrylamide plays a critical role in stabilizing the microstructure of sulfur, facilitating the integration and uniform formation of the composite coating. This innovative approach demonstrates the potential for creating robust composite materials with promising applications.
