| Abstract Scope |
Polyetheretherketone (PEEK) is a thermoplastic polymer that is used extensively in biomedical implants, but it has no inherent antimicrobial properties. The objective of the research is to determine the optimal spin coating parameters that can be used to effectively surface coat the additively manufactured PEEK substrates with silver nanoparticles (AgNPs) to add built-in antimicrobial characteristics to PEEK's unique properties. Furthermore, annealing at different temperatures is performed to study the effect on the mechanical properties and the dispersion of the AgNPs on the PEEK surface. Furthermore, a new fabrication approach is explored in which a layer of PEEK with an infill density ranging between 30% to 90% will be printed on top of the AgNPs surface-coated PEEK. This approach is anticipated to maintain the antimicrobial properties of the surface coating while providing some barrier between the AgNPs and human cells and reducing the wear of the AgNPs. |
