Front cover: In article 2200704 by Dmitrii Rusakov, Angelika Menner, and Alexander Bismarck, a high-temperature process with two high boiling point solvents allows to successfully create porous poly(ether ketone ketone) (PEKK) tunable properties, making it promising material for biomedical applications. The achieved porosities of 70 90%, specific surface areas up 194 m2 g−1, adjustable elastic ...

Polyaryletherketones (PAEK) are high-performance plastics with excellent mechanical properties and high thermal resistance used, e.g. as material for implants. Their molecular structure gives them a level of chemical inertness but prevents bonding adhesive interactions other materials integration into body tissue. Using the example poly(ether ether ketone) (PEEK), we show novel synthetic routes...

With the global effort to reduce fossil fuels and use eco-friendly energy, interest in Li-ion batteries (LIBs) is rapidly increasing. In LIB system, separator an important component for determining rate performance safety of cells. Although polyolefin separators are commercially used LIBs, they still suffer from inferior electrolyte wettability low thermal stability issues. Here, we introduce a...
