AbstractSince late 1990s, polyetheretherketone (PEEK) has presented a promising polymeric alternative to metal implant components, particularly in orthopedic and traumatic applications. However, PEEK is biologically inert, which has constrained its potential applications. In this manner, enhancing the bioactivity of PEEK is a huge challenge that must be comprehended to completely understand the potential advantages. Up to now, two noteworthy methodologies are discussed to enhance the bioactivity of PEEK, including bulk and surface modification. Although the latter is extremely challenging due to the very high physical and chemical stability of the high performance polymer, there are some stated modification reactions in the literature, which will be collocated with in the literature-reported PEEK composites in the present article. We will furthermore add information on polymer-based drug delivery systems and the biofunctionalization of polymers in general and discuss their applicability for PEEK, as we estimate that these strategies will gain greater attention in the future. At the end of the article, our own research on the development of a PEEK-associated biodegradable drug-delivery system with potential application in dentistry or orthopedics will be highlighted.

Taking into consideration the latest advances in both ceramic and polymer fields, a new generation of high-performance polymer composites based on the state-of-the-art MXene (Ti3C2(OH)2) ceramics and one of the leading high-performance thermosets, namely the phthalonitrile resins, is presented. The synergistic combination between the two phases led to nanocomposites exhibiting an outstanding thermal stability with starting decomposition temperatures not less than 484°C for 3 wt% of nanoloading. The tensile properties were as high as those obtained with fiber-reinforced polymer composites. For instance, the tensile strength reached its highest value of 276 MPa for the maximum loading of 3 wt%. The morphological studies carried out by scanning and transmission electron microscopies corroborated the improvements of the thermal and mechanical properties. Undoubtfully, such materials expected to be used in extreme conditions can be seen as the next generation of ceramics-reinforced polymer composites.
