Poly aryl-ether-ether-ketone (PEEK) is an alternative to metal alloys in orthopedic applications. Although the polymer provides many significant advantages such as excellent mechanical properties and non-toxicity, it suffers from insufficient elasticity and biocompatibility. Since the elastic modulus of diamond-like carbon (DLC) is closer to that of cortical bone than PEEK, the DLC/PEEK combina...

BACKGROUND Calcium sulphate (CS) has been used in bone grafting since the 1800s. It has not replaced autograft as the gold standard, however, since its dissolution occurs rapidly in bodily fluids, meaning that the material cannot support long-term bone growth. Here, the polymer poly (ether ether ketone) (PEEK) was used to slow dissolution in in vitro physiological environments and augment the m...

High molecular weight aromatic poly(ether ketone ketone)s were synthesized by the Friedel-Crafts polyacylation condensation of isoand terephthaloyl chlorides with diphenyl ether, 1,4and 1,3-bis(4phenoxybenzoyl)benzenes. Depending on the monomers used for polycondensation, polyketones of regular structure with different iso-/tereisomer repeating unit ratio (100/0, 50/50, 0/100) in the main chain...

Adhesion of regenerating bone tissue to orthopaedic implants is critical their long-term success. Titanium has excess rigidity, interferes with imaging, and complicates radiation treatment. Poly(ether-ether-ketone) (PEEK) a preferred material, but limited by biological inertness. We show that plasma immersion ion implantation (PIII) imparts osteoadhesion on 3D printed PEEK using in vitro pull-o...

Abstract The substantial heat generation due to miniaturization and high-degree integration of electronic devices is one the major issues facilitate efficient thermal management in power electronics. Though epoxy-based composites have shown great interest different applications such as laminated circuit board, component encapsulations, potting, they low application temperature (up 150 °C) highe...
