“…This thermoplastic possesses high temperature stability of upwards of 300 C, resistance to chemical and radiation damage, low moisture absorption, good dimensional stability and biocompatibility. [22][23][24] The average tensile strength and exural modulus of PEEK are 93 MPa and 4 GPa, respectively. However, with PEEK composites reinforced by hydroxyapatite or carbon bers, these properties can be tailored to the desired biomedical application.…”

The manuscript presents the use of tungsten disulfide inorganic nanotubes (INT-WS 2 ) to fabricate advanced poly(ether ether ketone) (PEEK) biomaterials by a traditional melt processing technique. This strategy offers an attractive way to combine the merits of organic and inorganic materials into novel hybrid systems with improved performance. The effect of INT-WS 2 content on the morphology, thermal stability, crystallization behaviour, thermal conductivity, mechanical and tribological properties is investigated in detail with various techniques. The results indicate that these inorganic nanotubes can be efficiently incorporated into the biopolymer matrix without the need for modifiers or surfactants, resulting in a very homogenous dispersion. Additionally, it is found that the increase in INT-WS 2 concentration leads to changes in the crystallization behaviour without modifying the crystalline structure of PEEK in the nanocomposites. The incorporation of INT-WS 2 produces higher improvements in the degradation temperature, storage modulus, thermal expansion coefficient, hardness, coefficient of friction and wear resistance of the polymer than the addition of other inorganic nanofillers or carbon nanotubes, providing an effective balance between performance, cost effectiveness and processability. These novel nanocomposites are of great interest for use in biomedical applications, particularly for orthopaedic and trauma implants.

“…Under isothermal conditions, the extent of crystallization (X) over time (t) in PEEK can be described by the Avrami relationship [34,38]: (1) where k relates the growth of nucleation in the polymer and n depends on the mechanism of nucleation. For PEEK, n = 3, and the k ranges over three orders of magnitude depending upon the temperature chosen for the isothermal crystallization experiment [34].…”

“…Following confirmation of its biocompatibility two decades ago [1], polyaryletherketones (PAEKs) have been increasingly employed as biomaterials for orthopedic, trauma, and spinal implants. Commercialized for industry in the 1980s, PAEK is a relatively new family of high temperature thermoplastic polymers, consisting of an aromatic backbone molecular chain, interconnected by ketone and ether functional groups [2].…”

Since the 1980s, polyaryletherketones (PAEKs) have been increasingly employed as biomaterials for trauma, orthopedic, and spinal implants. We have synthesized the extensive polymer science literature as it relates to structure, mechanical properties, and chemical resistance of PAEK biomaterials. With this foundation, one can more readily appreciate why this family of polymers will be inherently strong, inert, and biocompatible. Due to its relative inertness, PEEK biomaterials are an attractive platform upon which to develop novel bioactive materials, and some steps have already been taken in that direction, with the blending of HA and TCP into sintered PEEK. However, to date, blended HA-PEEK composites have involved a trade-off in mechanical properties in exchange for their increased bioactivity. PEEK has had the greatest clinical impact in the field of spine implant design, and PEEK is now broadly accepted as a radiolucent alternative to metallic biomaterials in the spine community. For mature fields, such as total joint replacements and fracture fixation implants, radiolucency is an attractive but not necessarily critical material feature.

“…PEEK can also be sterilized and shaped by machining to fit the contour of bones [22]. Consequently, PEEK has been widely used for load-bearing orthopedic applications, including dental implants, screws, and spinal interbody fusion cages [23,24].…”

Anticorrosive, Antimicrobial, and Bioactive Titanium Dioxide Coating for Surface‐modified Purpose on Biomedical Material

A multifunctional titanium dioxide (TiO 2 ) coating was used to provide anticorrosive, antimicrobial, and bioactive properties for the surface modification of biomedical materials because TiO 2 has a stable bonding structure, photocatalytic characteristics, and negatively charged surfaces in nature. For successful deposition, an arc ion plating technique was adopted to deposit the TiO 2 coating. The antimicrobial activity values of anataseTiO 2 -coated stainless steel specimens against Staphylococcus aureus and Escherichia coli were 3.0 and 2.5, respectively, which are far beyond the value designated in JIS Z2801:2000 industrial standard. TiO 2 coatings on stainless steel also generate an increased (i.e., less negative) corrosion potential and decreased corrosion current in a sodium chloride solution, showing a reduced tendency and rate of substrate dissolution as well as a reduced coating of species into the electrolyte. In addition, TiO 2 coatings, especially with rutile phase, satisfied the requirements for activating the biological property of a polymeric polyetheretherketone surface. Therefore, TiO 2 is a promising surface modification for the biomedical materials used in surgical instruments and implants.
