Developing Composite Coating of PEEK and AgNP on 316L Stainless Steel Substrate for Biomedical Implant

Abstract

Biomedical implants play a crucial role in modern healthcare, but their long-term success hinges on the materials used. This study focuses on developing a composite coating of polyetheretherketone (PEEK) and silver nanoparticles (AgNP) on 316L stainless steel substrates, aiming to enhance their biocompatibility and antibacterial properties. PEEK is known for its biocompatibility and mechanical properties, while AgNP exhibit excellent antibacterial activity. By combining these materials, we aim to create a coating that not only supports the integration of implants with surrounding tissue but also reduces the risk of infections, a common complication in implant surgery. The fabrication process involves depositing a PEEK layer on the stainless steel substrate, followed by the incorporation of AgNP using a suitable method such as electro spinning or dip coating. The coated substrates will undergo comprehensive characterization, including mechanical testing, surface analysis, and antibacterial efficacy assessment. The mechanical properties of the coating will be critical to ensure its durability and resistance to wear in the demanding environment of the human body. Furthermore, the chemical and biological properties of the coating will be evaluated to ensure its biocompatibility and safety for implantation. This study aims to contribute to the development of advanced coatings for biomedical implants, ultimately improving their performance and longevity. The findings of this research could lead to the development of safer and more effective biomedical implants, benefiting patients and healthcare systems worldwide.
