Polyether ether ketone (PEEK) is a biocompatible alternative to metallic biomaterials because of its unique properties and biocompatibility. Its bioinert nature may lead implant failure from inadequate osseointegration. Therefore, this research aims develop the nSiO2 ceramic particle-reinforced PEEK (nSiO2@PEEK) polymer nanocomposite. The particle size nanoparticles was measured as 43.6 nm usin...

Study Design Retrospective case series. Objective StaXx XD (Spine Wave, Inc., Shelton, CT, United States) is an expandable polyaryl-ether-ether-ketone (PEEK) wafer implant utilized in the treatment of lumbar degenerative disease. PEEK implants have been successfully used as interbody devices. Few studies have focused on expandable PEEK devices. The aim of the current study is to determine the r...

Front cover: In article 2200704 by Dmitrii Rusakov, Angelika Menner, and Alexander Bismarck, a high-temperature process with two high boiling point solvents allows to successfully create porous poly(ether ketone ketone) (PEKK) tunable properties, making it promising material for biomedical applications. The achieved porosities of 70 90%, specific surface areas up 194 m2 g−1, adjustable elastic ...

One of the important concerns about the quality of the thermoplastic composite in Automated Fiber Placement (AFP) process is the degradation of thermoplastic resin, resulting from the overheating or the lack of proper heating by the heating system used in the automated fiber placement machine head. Heat transfer between the heating system and incoming pre-impregnated tow is not easy to control ...

Poly(ether ketone ketone) (PEKK) is a semicrystalline polymer investigated for highly demanding applications in aerospace, transportation, electronics, and oil & gas industries. The properties required these applications, such as thermomechanical chemical stability, are intimately linked to the crystalline state of material. PEKK exhibits polymorphism that depends, among other factors, on its t...

Polyether ether ketone (PEEK) is considered the best alternative material for titanium for spinal fusion cage implants due to its low elasticity modulus and radiolucent property. The main problem of PEEK is its bioinert properties. Coating with hydroxyapatite (HA) showed very good improvement in bioactivity of the PEEK implants. However the existing methods for deposition of HA have some disadv...
