Bone defects resulting from trauma or disease remain a significant challenge in clinical practice, often requiring prolonged treatment. Poly(ether-ketone-ketone) (PEKK) is commonly used implant material due to its excellent biocompatibility and mechanical properties, which are similar those of bone. However, biological inertness leads poor anti-inflammatory osteointegration significantly hindering the bone repair process. In this study, cryogel filled - PEKK/bioglass (BG) composite scaffold (SPBC) was prepared via 3D printing provide immunomodulatory integration performance. Compared with untreated PEKK, SPBC exhibited enhancements surface including higher hydrophilicity roughness. Additionally, enhanced adsorption fibronectin vitronectin on regulated maturation cytoskeleton adhesion plaques by increasing phosphorylation level FAK at Y397, thereby promoting cell spreading. Due release bioactive ions, can promote polarization RAW264.7 cells towards M2 secretion cytokines, while also enhancing proliferation differentiation rat mesenchymal stem (rMSCs) vitro. Furthermore, vivo results confirmed properties host tissue. summary, after modification filling, demonstrated abilities, presenting potential for application as an orthopedic scaffold.

Carbon-fiber-reinforced PEEK matrix composites are exposed to hydrothermal aging owing their working areas. Therefore, it is important understand how the mechanical properties of material change during as a design criterion. Firstly, composite samples were quenched reset thermal history. Heat treatment (annealing) was applied carbon fiber-reinforced polyetheretherketone (CF/PEEK) at 305°C for 270 min. After quenching. Subsequently, process 80°C 45 and 90 days. It observed that crystallinity fiber/matrix interface CF/PEEK changed significantly with previous history material. There an increase in degree heat aging. The flexural strength values all materials decreased after However, decrease more amorphous structure quenching greater than heat-treated before DMA results show reduces fiber–matrix bond both materials. On other hand, tanδ much lower those materials, expected. This indicates interfacial adhesion stronger samples. test supported by scanning electron microscopy (SEM) images obtained from fractured surfaces result test.
