“…Improvement of the bioadhesion properties could possibly result from an increase of the surface hydrophilicity, for instance by the introduction of carboxyl groups or by UV irradiation. In such a way, these reactive surface functionalisations should be excellent anchorage points for the immobilization of bioactive molecules [4][5][6].…”

Poly-ether-ether-ketone (PEEK) is a high performance polymer with many intrinsic properties. When it is used in the form of coating, an improvement of some of its functional properties was achieved by forming a surface nanolayer. In this chapter, it will be described how it was possible to obtain this result. Firstly, three kinds of PEEK composite coatings were deposited by electrophoretic deposition, adding alumina particles, polytetrafluoroethylene (PTFE) and lignin to PEEK. Then, the composite coatings were thermal treated in a furnace. Therefore, surface nanostructure and chemical composition of these PEEK composite coatings were modified with respect to bulk coatings, due to interaction between PEEK chain and secondary phase, emphasised by the thermal treatment conditions. Experimental evidence of the formation of surface nanolayer was provided by SEM, TEM, GIXRD, ATR-FTIR and XPS characterisations. Functional characterisations demonstrated that wear resistance-in the presence of alumina particles-hydrophobicity-in the presence of PTFE-and corrosion resistance-in the presence of Lignin-were increased with respect to pure PEEK.

“…Plasma technology was used to enhance the attachment of fibroblasts and bone cells to modified material [2]. Basic research using various photochemical routes was explored which may open up further ways for the enhancement of cell adhesiveness [3]. A highly promising and purely wet-chemical approach is based upon the generation of hydroxy functionalities via reduction of the keto groups of the benzophenone repeating units of the PEEK polymer backbone in order to generate hydroxy functions [4].…”

In recent years, the synthetic polymer polyetheretherketone (PEEK) has increasingly been used in a number of orthopedic implementations, due to its excellent mechanical properties, bioinertness, and chemical resistance. For in vivo applications, the surface of PEEK, which does not naturally support cell adhesion, has to be modified to improve tissue integration. In the present work we demonstrate a novel wet-chemical modification of PEEK to modify the surface, enabling the covalent grafting of the cell-adhesive RGD-peptide. Modification of the polymer surface was achieved via Schiff base formation using an aliphatic diamine and subsequent crosslinker-mediated immobilization of the peptide. In cell culture experiments with primary osteoblasts it was shown that the RGD-modified PEEK not only significantly promoted cellular adhesion but also strongly enhanced the proliferation of osteoblasts on the modified polymer surface.

“…[1][2][3][4] Because PEEK has mechanical strength and is light, it may be used as a biomaterial, i.e., a material designed and manufactured to be placed in contact with living tissue, cells, blood, and various biological fluids. 5,6) PEEK possesses two units, a phenyl ether group and a benzophenone group, with an oxygen atom and a carbonyl group (C=O) existing between the two phenyl groups. The C-O bond in the phenyl ether group and the C-C bond in the benzophenone group are weak because the electronegativity of oxygen elements is strong and the phenyl and carbonyl groups (C=O) have resonant structures.…”

To minimize degradation reactions occurring at the same time as surface modification reactions, the surface modification of poly(aryl ether ether ketone) (PEEK) film surfaces by pulsed oxygen plasma was investigated. Oxygen radicals and ion and electron concentrations in the oxygen plasma were calculated as a function of the elapsed time after the discharge was turned off. The pulsed plasmas showed a low contact angle compared to those treated with continuous plasma, though the weight loss of the pulsed plasma irradiated sample decreased compared to those irradiated by continuous plasma. X-ray photoelectron spectra (XPS) measurements indicated that oxygen groups were formed on the PEEK surface.
