The rapid evolution of medical device technologies has provided effective solutions to several health challenges, ranging from artificial heart valves to hip replacement prostheses. Despite advancements in medical device technologies, infections remain a critical concern, posing risks such as tissue damage and organ failure. To address this, biomaterials with enhanced bactericidal properties are crucial.

This study examined the effectiveness of the produced elastomeric coatings containing bactericidal additives, in preventing bacterial infections on the surfaces of materials used in medicine. The influence of various additives, including silver, turmeric, graphene, cloves, and black cumin seeds, was tested on the bactericidal properties of silicone coatings. The bactericidal tests carried out showed an effect dependent on their concentration, and samples containing silver and black cumin seeds showed the strongest bactericidal properties. However, optimal concentrations must balance bactericidal effectiveness with potential cytotoxicity concerns. The material tests carried out focused on understanding the impact of additives such as silver, turmeric, graphene and cloves on the properties of the elastomer, revealing their diverse impact on the chemical structure, surface morphology, hardness, and hydrophobicity. The analysis of the surface adhesion of polymer coatings to glass proved that the use of additives improves their adhesion to the substrate used. The strongest effect was visible when turmeric was added to the silicone matrix.
