Polyetheretherketone (PEEK) materials belong to a group of high-performance thermoplastic polymers thermoplastic that has been proposed as a substitute for metals in biomaterials. In this research. in order to improve the performances of PEEK. nano titanium dioxide (n-TiO2) and nano-hydroxyapatite (n-HAp) were incorporated into PEEK loading up to (1. https://www.mariameetsanna.com/product-category/10b/
