In this report, the bromination of poly(ether ether ketone) (PEEK) using mild reagent N-bromosuccinimide (NBS) is explored to generate controlled random and blocky microstructures. Bromination proceeded quantitatively in both solution state semicrystalline gel-state, degrees between 25 175 mol% were obtained for BrPEEK. Spectroscopic evidence revealed a higher prevalence unfunctionalized repeat...

A nanostructure of graphene oxide (GO) and carbon nanotubes (CNTs) decorated with silver nanoparticles (AgGNT) has been prepared via a molecular-level-mixing (MLM) method followed by subsequent freeze-drying reduction process. The obtained well-dispersed AgGNT nanostructures were then applied as fillers to reinforce the poly(ether ether ketone) (PEEK) matrix. AgGNT-PEEK composites have demonstr...

Polyaryletherketones (PAEK) are high-performance plastics with excellent mechanical properties and high thermal resistance used, e.g. as material for implants. Their molecular structure gives them a level of chemical inertness but prevents bonding adhesive interactions other materials integration into body tissue. Using the example poly(ether ether ketone) (PEEK), we show novel synthetic routes...

The effects of surface modifications of multi-walled carbon nanotubes (MWCNTs) on the morphology, dynamic mechanical and tribological properties of multi-walled carbon nanotube/poly (ether ether ketone) (MWCNT/PEEK) composites have been investigated. MWCNTs were treated with mixed acids to obtain acid-functionalized MWCNTs. Then the acid-functionalized MWCNTs were modified with ethanolamine (na...

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...

A new innovative low-wear bearing for use in total hip arthroplasty, a wear couple consisting of carbon fiber-reinforced poly-ether-ether-ketone (CF-PEEK), has been shown to be highly biocompatible and to have excellent tribological performance in the laboratory. We report the results of our technical and histologic analysis of a CF-PEEK composite acetabular cup component articulating against a...

The reliable assembly of poly-ether-ether-ketone (PEEK) and carbon fiber-reinforced PEEK (CFR-PEEK) is crucial to effective load transfer within lightweight high-stiffness structures, which are commonly demanded in aeronautical, automobile, medical industries. In this work, laser transmission welding CFR-PEEK has been performed by using a 1070 nm Nd:YAG fiber laser. effects process parameters i...
