Schematic representation of the ultrafast EC device based on PEDOT nanotube arrays. Anions (negatively charged gray balls) diffuse into the thin wall (10–20 nm in wall thickness to provide the short diffusion distance) of the PEDOT nanotubes when PEDOT nanotubes are oxidized by applying a positive potential. The color of PEDOT turns from a deep blue to a transparent pale blue. Reproduced with permission from Ref. [52]; Copyright 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
