“…Thus, the interphase thickness remained at ∼120 nm after 8 h of hydrothermal treatment and the epoxy matrix absorbed water continuously. To the contrary, due to much better hydrothermal stability of the phenyl ether and benzophenone groups , the change of the interphase dimensions of T300/PEEK under boiling water was only 13.2% upon 24 h degradation treatment. This results are consistent to the previous studies that the PEEK polymer and PEEK composites were highly resistant to environmental effects .…”

In order to understand the role of interphase in polymer‐matrix composites, a Peak Force Quantitative Nanomechanics technique based on atomic force microscopy was applied to explore the structures and mechanical properties of the interphase region in carbon fiber reinforced poly(ether‐ether‐ketone) (T300/PEEK) and carbon fiber reinforced epoxy (T700/epoxy) composites. The quantitative topographies and elastic modulus maps of each phase of the composites were acquired after 4, 8, 12, 18, and 24 h of hydrothermal ageing. The interphase thickness of T300/PEEK increased from 68.1 ± 10.9 to 76.9 ± 17.0 nm after 8 h of degradation and kept stable at 78.2 ± 18.6 nm, while that of T700/epoxy increased from 45.2 ± 4.1 to 110.8 ± 13.8 nm in the first 8 h and remain stable until 24 h of degradation. Moreover, the moduli of PEEK matrix and epoxy matrix presented a steady and continuous decrease, respectively, during the hydrothermal ageing process and the enlargement of interphase thickness can be attributed to the plasticizing and hydrolytic effects.

“…This can be used for a lot of further synthesis reactions, such as the grafting of different polymer chains on the surface of PEEK ( Figure 6 ). Using this method, it was possible to functionalize the PEEK surface with polystyrene (PS), vinyl phosphonic acid (VPA), butyl acrylate (BA), acrylic acid (AA), polyacrylic acid (PAA), and monomethoxy‐terminated oligo (ethylene glycol) methacrylate (MeOEGMA) …”

Polyetheretherketone (PEEK) is a promising implant material because of its excellent mechanical characteristics. Although this polymer is a standard material in spinal applications, PEEK is not in use in the manufacturing of dental implants, where titanium is still the most‐used material. This may be caused by its relative bio‐inertness. By the use of various surface modification techniques, efforts have been made to enhance its osseointegrative characteristics to enable the polymer to be used in dentistry. In this feature paper, the state‐of‐the‐art for dental implants is given and different surface modification techniques of PEEK are discussed. The focus will lie on a covalently attached surface layer mimicking natural bone. The usage of such covalently anchored biomimetic composite materials combines many advantageous properties: A biocompatible organic matrix and a mineral component provide the cells with a surrounding close to natural bone. Bone‐related cells may not recognize the implant as a foreign body and therefore, may heal and integrate faster and more firmly. Because neither metal‐based nor ceramics are ideal material candidates for a dental implant, the combination of PEEK and a covalently anchored mineralized biopolymer layer may be the start of the desired evolution in dental surgery.

“…Several works in the literature have assessed the influence of “brush‐like” structure on the tribological properties. UV irradiation is conductive to generate free radicals on the surface benzophenone unit where various polymer chains can be grafted to form this structure …”

Poly(ether-ether-ketone) (PEEK) is a known bio-implant material due to its excellent mechanical properties. However, the challenging issue of high friction coefficient limits the PEEK applications. In this article, double-layered hydrogel material was obtained by laser processing, surface sulfonation, and poly(vinyl alcohol) (PVA) casting. Characterizations of FT-IR, XRD, SEM, and 3Dmorphology demonstrate that PVA-LSPEEK hydrogel was achieved successfully. PVA-LSPEEK exhibits an extremely smooth surface with a roughness of 0.079 μm. And this hydrogel presents an excellent mechanical adhesion to PEEK substrate, forming a soft-hard structure. Tribological properties of PVA-LSPEEK are improved drastically when compared to the PEEK substrate. This innovative hydrogel material provides a potential application in articular cartilage defect repair.
