“…S1). The guest MWNT aerogel sheet strips were drawn from special CNT forests that are drawable 24 , and the conducting polymer yarn guest was subsequently deposited by vapour phase polymerization (VPP), which is a well-known method for providing uniform coatings of highly conducting polymer layers on substrates 25 . In the present case, the coated substrate structure is three-dimensional, as the conducting polymer coats MWNTs and MWNT bundles within the host sheet.…”

Flexible, wearable, implantable and easily reconfigurable supercapacitors delivering high energy and power densities are needed for electronic devices. Here we demonstrate weavable, sewable, knottable and braidable yarns that function as high performance electrodes of redox supercapacitors. A novel technology, gradient biscrolling, provides fastion-transport yarn in which hundreds of layers of conducting-polymer-infiltrated carbon nanotube sheet are scrolled into B20 mm diameter yarn. Plying the biscrolled yarn with a metal wire current collector increases power generation capabilities. The volumetric capacitance is high (up to B179 F cm À 3 ) and the discharge current of the plied yarn supercapacitor linearly increases with voltage scan rate up to B80 Vs À 1 and B20 Vs À 1 for liquid and solid electrolytes, respectively. The exceptionally high energy and power densities for the complete supercapacitor, and high cycle life that little depends on winding or sewing (92%, 99% after 10,000 cycles, respectively) are important for the applications in electronic textiles.

Ultrathin (thicknessnm) electrically conducting membranes can be used as electrodes for sensors, actuators, optical devices, fuel cells, scaffolds for assembling nanoparticles, and separation of biological macromolecules.1-6 Various approaches have been suggested for the fabrication of free-standing nanomembranes based on organic polymers and/or inorganic materials: spin-casting of films,7 layer-by-layer assembly of polyelectrolyte multilayers,8 cross-linking of self-assembled monolayers,9 and assembly of triblock copolymers.10,11 Loading materials such as gold nanoparticles12 or carbon nanotubes13 make membranes robust and electrically conductive. However, these methods are often time-consuming and have some limitations in terms of achievable electrical and electrochemical membrane performance as well as scaleup. Alternative approaches are needed for the preparation of mechanically robust, free-standing, conductive nanomembranes that could be easily manufactured. ABSTRACTWe report mechanically robust, electrically conductive, free-standing, and transparent hybrid

“…Winther-Jensen and West demonstrated the use of the FTS oxidant with pyridine as a weak base inhibitor during VPP to strengthen the electrical conductivity of PEDOT films. 18,25 Further studies employing imidazole to raise the pH of the oxidant also determined that, as the base evaporates from the oxidant, a more controlled polymerization was triggered. 15,26 Meanwhile, Fabretto et al suggested the role of water during the VPP process.…”

This paper reports the combined effects of the triblock copolymer surfactant poly(ethylene glycol)-poly(propylene glycol)-poly(ethylene glycol) (PEG-PPG-PEG) and imidazole on the opto-electrical and mechanical properties of poly(3,4-ethylenedioxythiophene) (PEDOT)-based thin films prepared via vapor phase polymerization (VPP) using ferric p-toluenesulfonate as a catalyst. Various PEDOT-based thin films were synthesized using PEG-PPG-PEG and imidazole alone and in combination to compare and correlate their effects on film properties. The improved conductivity of the PEDOT films was higher than 1300 S·cm -1 when the surfactant and imidazole were used together. The PEG-PPG-PEG chain length was also varied to identify the best conditions for the VPP-based preparation of PEDOT thin films.
