“…The main structure of SPEEK and PEEK was observed to be similar. Although the benzene ring skeleton is not destroyed, its vibration frequency is affected by the substituent . Further examination exhibited extra characteristic polymer bands from SPEEK, such as SO symmetric stretching at 1022 cm −1 and OSO dissymmetric stretching at 1260 cm −1 .…”

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.

Purpose Evaluation of the available research on PEEK materials to find that whether PEEK material has favorable properties and can enhance osseointegration, so that they can be utilize as implants material. Materials and Methods An electronic and structured systematic search was undertaken in May 2018, without any restrictions of time in the Medline/Pubmed, Sci‐hub, Ebscohost, Cochrane, and Web of Science databases. To identify other related references further hand search was done. Articles related to PEEK and their applications in implants were only included. Articles not available in abstract form and article other than English language were excluded. Results Initially, the search resulted in 153 papers. Independent screenings of the abstracts were done by the reviewers to identify the articles related to the question in focus. Sixty‐two studies were selected out of which 10 were further excluded due to not in English language. Two additional papers were obtained after hand searching, and finally 54 articles were included in the review. Conclusions Surface modification of PEEK seems to enhance the cell adhesion, proliferation, biocompability, and osteogenic properties of PEEK implant materials. PEEK had also influence the biofilm structure and reduces the chances of periimplant inflammations. Further research and more number of controlled clinical trials on PEEK implant is required in near future so that it can replace titanium in future.

“…On the other hand, this coating has antibiofouling properties due to the composition of the SPEEK coating, which is based on S-content. Montero and co-workers evaluated the degree of sulfonation on bacteria biofilm formation, and they observed that more than two-to-three hours of sulfonation reduced biofilm formation [53], which can also be seen in Figure 12 due to the absence of colonies in the agar plates. Though the role of sulfur on the bioactivity could be questioned, several reports have confirmed that sulfonation treatment followed by simulated body fluid incubation had a significant positive impact on osteointegration [55].…”

“…This polymeric coating has been previously evaluated in terms of cell biocompatibility and osteoblast differentiation in several studies [53,54]. As a bioactive coating, putting SPEEK onto titanium substrates has shown suitable properties for bone and dental applications as well as for reducing bacterial infections [53]. To confirm the antibiofouling activity of the SPEEK coating and to include a chemical surface modification as an interesting strategy to reduce or control bacterial infection on porous substrates, SPEEK-coated and uncoated porous surfaces were compared.…”

Here, titanium porous substrates were fabricated by a space holder technique. The relationship between microstructural characteristics (pore equivalent diameter, mean free-path between pores, roughness and contact surface), mechanical properties (Young’s modulus, yield strength and dynamic micro-hardness) and bacterial behavior are discussed. The bacterial strains evaluated are often found on dental implants: Methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa. The colony-forming units increased with the size of the spacer for both types of studied strains. An antibiofouling synthetic coating based on a sulfonated polyetheretherketone polymer revealed an effective chemical surface modification for inhibiting MRSA adhesion and growth. These findings collectively suggest that porous titanium implants designed with a pore size of 100–200 µm can be considered most suitable, assuring the best biomechanical and bifunctional anti-bacterial properties.
