The Cover Feature shows an image of polypyrrole and oxidized multi‐walled carbon nanotubes composite overlaid by a schematic illustration of the charge density at the interphase and a voltammetric response of the composite. During the composite formation, multi‐walled carbon nanotubes act as an oxidizing agent and initiate polymerization process. The polymeric phase is deposited both at the surface of carbon nanotubes and in the empty spaces of MWCNTs network. The charge transfer at the interphase between both components of composite influences the electrochemical properties of formed material. More information can be found in the Article by M.
