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...

Poly-ether-ether-ketone (PEEK) fabricated by fused deposition modeling for medical applications was evaluated in terms of mechanical strength and in vitro cytotoxicity in this study. Orthogonal experiments were firstly designed to investigate the significant factors on tensile strength. Nozzle temperature, platform temperature, and the filament diameter were tightly controlled for improved mech...

A highly ion-selective membrane for vanadium redox flow batteries (VRBs) consisting of sulfonated poly(arylene ether ketone) (SPAEK) and polyoxometalate coupled with a graphene oxide was designed and fabricated. The SPAEK/PW-mGO composite membrane showed an effectively low self-discharge rate and excellent Coulombic efficiency (98.73%) in VRBs.

Appropriate preparation routes allow designing and improving the performances of ceramic-based functional composites. In this work, two powder-preparation methods enabled by cold sintering process are utilized to fabricate unique ZnO-based varistor The thermoplastic polymer, poly-ether-ether-ketone (PEEK), has been successfully integrated with ZnO form dense ZnO-PEEK With a dissolution method, ...

Compared to the common selective laser sintering (SLS) manufacturing method, fused deposition modeling (FDM) seems to be an economical and efficient three-dimensional (3D) printing method for high temperature polymer materials in medical applications. In this work, a customized FDM system was developed for polyether-ether-ketone (PEEK) materials printing. The effects of printing speed, layer th...
