Antibacterial Properties of PEKK for Orthopedic Applications [Erratum]
International Journal of Nanomedicine, 2022 Wang M, Bhardwaj G, Webster TJ. Int J Nanomedicine. 2017;12:6471–6476. An error during the preparation of Figure 6 for publishing led to the inadvertent creation of duplicate features in the PEEK image and alterations in the PEKK image on page 6475.

Evolution of mechanical properties of aged poly(ether ketone ketone) explained by a microstructural approach [PDF]
, 2021 In this work, the thermo-oxidative behavior of PEKK films (~50 µm thick) in solid state were investigated. Since the mechanical properties of PEKK samples, especially the strain at break, are clearly affected after long ageing time, the modifications of ...
