Abstract Polyether ether ketone (PEEK) is a widely used material for friction pairs due to its excellent mechanical strength, good wear resistance, and chemical inertness. However, some modifications are necessary when PEEK as water-lubricated pair. In this study, novel sulfonation method was developed design pair with ultralow friction, high loading capacity. powders were sulfonated using ClSO...

The study describes a homogenisation technique of developing Polyether ether ketone (PEEK) and calcium hydroxyapatite (cHAp) composite with periodic pattern lattice structures. continuum depiction the discrete structures was evaluated to retain PEEK cellulose properties cell applied dental implants. Design approaches were considered, using different software modelling optimise orthotropic mater...

STATEMENT OF PROBLEM Poly-ether-ether-ketone (PEEK), a high-performance semi-crystalline thermoplastic polymer, has been employed to replace the metallic implant components in orthopedics. There were various studies performed in accordance to medical grade PEEK, but the relationship between titanium dioxide (TiO2)-coated PEEK, TiO2-blended PEEK, and untreated PEEK still remains complicated, eve...

Biobased monomers derived from castor oil as well as from limonene suitable for thiol–ene copolymerization were synthesized. Di‐10‐undecenylether 2 was obtained via GaBr3‐catalyzed reduction of 10‐undecenyl 10‐undecenoate 1. Diene ether 2 and (R)‐limonene 5 were reacted in two steps using radical thiol–ene addition reactions to dithiol ether 4 and dithiol 7, respectively. Diene ether 2 and dith...

This study evaluated the influence of conventional and alternative surface treatments on wettability bond strength between polyether ether ketone (PEEK) veneering resin. PEEK samples were randomly divided into five groups: sandblasting, tribochemical silica coating, etching with 98% sulfuric acid for 5 s, 30 coating plus heated silane. One them was subjected to analysis by energy-dispersive X-r...

Abstract The purpose of this study was to increase the limited wear resistance polymers in highly stressed tribological contacts. Therefore, diamond-like carbon (DLC) coatings were firstly developed and deposited on polymers. development low temperature coating process conducted an industrial scale unit. Due use polyether ether ketone (PEEK) polyamide as substrate material, tailored accordance ...
