This study aims to investigate the mechanical performance and bioactive potential of polyetheretherketone (PEEK)-based composites. PEEK powder is mixed with up 20 wt-% zinc doped nano-hydroxyapatite (ZnHA) extrude filaments. Subsequently, 3D-printed samples are prepared via fused deposition modelling (FDM). Micro-Computed Tomography (µ-CT) analysis shows distribution ZnHA particles in extruded ...

Only time hav...

Poly‐ether‐ether‐ketone (PEEK) is a biocompatible, high‐strength polymer with biomechanical properties similar to soft bone that has been proposed as an alternative titanium for orthopedic implants. Herein, micro‐CT imaging of 3D printed PEEK scaffold treated plasma immersion ion implantation (PIII) assess the degree osteoconduction relative identical untreated structure, by in scapula sheep, p...

Polyether ether ketone (PEEK) is a biocompatible alternative to metallic biomaterials because of its unique properties and biocompatibility. Its bioinert nature may lead implant failure from inadequate osseointegration. Therefore, this research aims develop the nSiO2 ceramic particle-reinforced PEEK (nSiO2@PEEK) polymer nanocomposite. The particle size nanoparticles was measured as 43.6 nm usin...

Poly-Ether-Ketone (PEEK) is a bioactive material capable of replacing traditional metal and ceramic components in biomedical applications but still lacks some strength biological propertices compared with natural bone. In this research, calcium hydroxyapatite (cHAp) reduced Graphene oxide (rGO) were combined PEEK, different lattice porose structures produced to improve interfaces biocompatibili...

Background: Surgery for bone tumors around the knee often involves extensive resection, making subsequent prosthetic reconstruction challenging. While carbon fiber-reinforced polyetheretherketone (CF-PEEK) has been widely used in orthopedic implants, its application tumor-type prosthesis is limited. This study aims to evaluate feasibility of using 30wt% and 60wt% (CF30-PEEK CF60-PEEK) as materi...
