PEEK Biomaterials Handbook

A new textbook dedicated to PEEK Biomaterials, edited by Dr. Steve Kurtz, has been published as part of the Plastics Design Library by Elsevier Inc.This Handbook brings together experts in many different facets related to PEEK clinical performance as well as in the areas of materials science, tribology, and biology to provide a complete reference for specialists in the field of plastics, biomaterials, medical device design and surgical applications. This book can be preordered at Amazon.

Mechancial Properties and Bioactivity of PEEK-OPTIMA/Hydroxyapatite Compounds

This study describes an industrially relevant route for the production of a PEEK/HA (20% by weight) compound through twin-screw compounding, without significant loss of the advantageous mechanical properties of PEEK. Additionally researchers have demonstrated increased Ca/P deposition on this compound folloiwng immedsion in simulated body fluid, indicative of  the potential for increased bony integration in vivo.

Characterization of PEEK Biomaterials using the Small Punch Test

This study was conducted to investigate the suitability of the small punch test for characterizing polyetheretherketone (PEEK) polymeric biomaterials for changes in material grade, crystallinity, and molding process. The small punch test reproducibly characterized the mechanical behavior of PEEK and was able to distinguish differences induced by molding process alterations and annealing. The results of this study validate the small punch test as a repeatable method for measuring mechanical behavior of PEEK biomaterials.

MD&M West 2011 Presentation: Precision Micro-Molding of PEEK components

This presentation by Scott Herbert from Rapidwerks describes micromolding as a viable solution for prototypes, small production and volume production of PEEK components. Micromolding of PEEK presents an ability to provide intricate and detailed geometry to a micropart without adding cost and providing savings in material usage.

MD&M West 2011 Presentation: Anti–Microbial PEEK Solutions

This MD&M presentation focuses on bacterial adhesion and proliferation on PEEK as well as methods of biofilm prevention. Research has been conducted into bacterial adhesion profiles on surface topography, and also the influences of oxygen plasma treatment on surface adherence. Various coating technologies reported in the literature attempt to put bone attachment at a competitive advantage to bacterial adhesion and promote antibiofouling behavior. Finally, studies are being performed to evaluate active responses to microbial intrusion with both antibacterial silver-PEEK composites and possible antibiotic tethering to PEEK surfaces.
