Special issue: PAEKing ahead into the 21st century.

As the material extrusion technology overlaps with composite manufacturing, some of the papers examined processing of PEEK composite materials. As the field of macromolecular science celebrated its 100th anniversary in 2020, we organised a special issue of Polymer International devoted to the synthesis, processing and applications of polyaryletherketones (PAEKs). A further area of research not particularly highlighted within this review; but very much an active concern; is the development of PAEK-based thermoplastic composites for application in the aerospace and medical sectors.
