High-temperature laser sintering (HT-LS) is a very promising additive manufacturing process for the production of parts complex geometry highly demanding applications. Poly(aryl ether ketone) polymers such as poly(ether ketone), and ketone (PEKK) have attracted increasing interest during last decade use in HT-LS. Among them, PEKK offers advantage exhibiting tunable melting temperature crystalli...

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...

Total hip replacement has been a successful surgical intervention for many years. However, concerns regarding UHMWPE wear particle induced osteolysis [1], have led to alternative bearing materials to be sought. Carbon-fibre reinforced poly-ether-ether-ketone (CFR-PEEK) is a fibre-reinforced polymer which has shown reduced wear in hip and knee configurations compared with conventional polyethyle...

INTRODUCTION Concerns regarding UHMWPE wear particle induced osteolysis [1] have led to investigations of alternative bearing materials. Carbon-fibre reinforced poly-ether-ether-ketone (CFR-PEEK) has been shown in animal studies to have a similar biological activity to UHMWPE [2], whilst hip and knee configurations incorporating this polymer display reduced wear rates when compared with convent...
