A Review on Developing Polyetheretherketone (PEEK) and Silver Nanoparticles (AgNP) Composite Coating on 316L Stainless Steel Substrate for Biomedical Implant

Abstract

Biomaterial science involves of study related to medicine, chemistry, biology, material science and tissue engineering. A variety of materials, including metals, ceramics, composites and polymers, are used for manufacturing bioimplants. These implants face a variety of biological settings with varying physical-chemical characteristics, and how they interact with bones and tissues is a difficult problem. The implant needs to meet a number of requirements, including high corrosion resistance, biocompatibility, appropriate mechanical qualities, osteointegration, recipient health, and surgical skill. Blood and other bodily fluid components, which include plasma, proteins, water, chlorine, amino acids and salt, provide a serious corrosion risk to the implants. As per the study of failed stainless implants found that stress corrosion cracking, pitting-induced fatigue fracture, and corrosion from crevice attack account for about 70% of type 316L SS implant failures. PEEK has high X-ray transparency, stable physical and chemical characteristics, and mechanical properties similar to human bones. Surface modification of biomedical implants are frequently undertaken to enhance surface texture, biocompatibility, wear resistance, and corrosion resistance. AgNPs with high antibacterial effectiveness are widely employed in implant surface modification to avoid implant-related infections.
