Researchers have created scaffolds with enhanced strength by fabricating 20 vol% polydopamine-modified nano hydroxyapatite (pDA-nHA), featuring a distinctive lamellar structure. These scaffolds were then immersed in a polyetherketoneketone (PEKK) synthesis system for reinforcement, offering an innovative approach to both augment the mechanical robustness of the material and enhance the bioactivity of PEKK.
