The family of semi-crystalline, aromatic, high-temperature thermoplastics known as poly(ether-ketone)s are insoluble in conventional organic solvents, but undergo completely general and quantitatively reversible reactions with alkanedithiols in strong acid media, to give soluble poly(dithioacetal)s, which are readily characterisable by GPC and light scattering techniques.

Polyether-ether-ketone (PEEK) is an alternative to metal alloys in orthopaedic applications. It gives significant advantages including excellent mechanical properties and non-toxicity. In this work, a set of specimens with different notched radii were selected to examine the effect of triaxial state of stress on the fracture behavior of PEEK. Fractographic analysis via scanning electron microsc...

This study aims to assess the biomechanical behavior of alveolar bone surrounding implants over protocol with metal, Polyether ether ketone (PEEK) and Zantex bars, in normal osteoporotic conditions. For simulation, geometric models mandibular arch were designed containing 5 two variables. The first variable is condition - osteoporotic-, second material used bars – PEEK Zantex. Simulation was pe...

High energy density, high temperature, and low loss dielectric polymers have drawn increasing attention in research owing to their potential applications power electronic pulsed devices. In this study, a new class of organo-soluble dipolar glass (DGPs) are synthesized via polycondensation post-functionalization poly(aryl ether)s (PAEs) based on phenolphthalin. Due the nonplanar backbone structu...

In the present study, friction and wear behaviors of Si3N4-hBN(Hexagonal boron nitride) ceramic composites against polyether-etherketone in artificial seawater were investigated, sliding speed was varied from 0.52 to 1.73 m/s study effect. It found that coefficients rates decreased with increase for Si3N4-hBN (with hBN content ranging 5% 20%) PEEK(Polyether-ether-ketone); pairs represented an u...
