“…There are a number of methods reported in the literature for polymerisation of EDOT 22,52,54 , including electrochemical polymerisation 52 ; room temperature emulsion (co)polymerisation of EDOT with NaPSS in the presence of Fe(NO3)3 (Scheme 1a) 22 and room temperature polymerisation in FeCl3-methanol solution (Scheme 1b) 23 . For preliminary studies, the two last methods have been explored, as shown in S cheme 1.…”

This paper addresses the challenge of producing multifunctional composites that can simultaneously carry mechanical loads whilst storing (and delivering) electrical energy. The embodiment is a structural supercapacitor built around laminated structural carbon fibre (CF) fabrics. Each cell consists of two modified structural CF fabric electrodes, separated by a structural glass fibre fabric or polymer membrane, infused with a multifunctional polymeric electrolyte. Rather than using conventional activated carbon fibres, structural carbon fibres were treated to produce a mechanically robust, high surface area material, using a variety of methods, including direct etching, carbon nanotube sizing, and carbon nanotube in situ growth. One of the most promising approaches is to integrate a porous bicontinuous monolithic carbon aerogel (CAG) throughout the matrix. This nanostructured matrix both provides a dramatic increase in active surface area of the electrodes, and has the potential to address mechanical issues associated with matrix-dominated failures. The effect of the initial reaction mixture composition is assessed for both the CAG modified carbon fibre electrodes and resulting devices. A low temperature CAG modification of carbon fibres was evaluated using poly(3,4-ethylenedioxythiophene) (PEDOT) to enhance the electrochemical performance. For the multifunctional structural electrolyte, simple crosslinked gels have been replaced with bicontinuous structural epoxy-ionic liquid hybrids that offer a much better balance between the conflicting demands of rigidity and molecular motion. The formation of both aerogel precursors and the multifunctional electrolyte are described, including the influence of key components, and the defining characteristics of the products. Working structural supercapacitor composite prototypes have been produced and characterised electrochemically. The effect of introducing the necessary multifunctional resin on the mechanical properties has also been assessed. Larger scale demonstrators have been produced including a full size car boot/trunk lid.

Makroporöse Schwämme sind eine Chance und Herausforderung für die Chemie und Materialwissenschaften. Die Herausforderung liegt in der Herstellung der Schwämme, die bestimmte Eigenschaftskombinationen aufweisen und zu neuen Anwendungen führen. Kennzeichnend für derartige Schwämme sind geringes Gewicht, Atmungsaktivität, spezielle Benetzungseigenschaften, großer Massentransfer, mechanische Stabilität und große Porenvolumina. Bottom‐up‐ und Top‐down‐Methoden zur Herstellung von Schwämmen aus Kohlenstoff und Polymeren sowie ausgewählte Eigenschaften und mögliche Anwendungen werden in diesem Aufsatz diskutiert.
