Abstract: In order to improve the electrochromic performance of polyaniline (PANI), porous PANI/vanadium carbide MXene (PANI/V2CTx) composite electrochromic films were prepared via a rapid, facile, and low-cost one-pot electrodeposition method from an aqueous solution composed of aniline and V2CTx for the first time. The addition of V2CTx with a 2D layered structure results in the PANI/V2CTx composite films exhibiting significantly different morphologies, structures, electrochemical and electrochromic properties from the pure PANI film. The results show that compared with the pure PANI film, the composite film with optimum V2CTx content possesses superior electrochromic properties, such as higher optical contrast, switching speed, coloration efficiency, and cycling stability. The improved electrochromic properties of the composite film can be ascribed to its unique porous morphology and strong hydrogen bond and/or electrostatic interaction between PANI and V2CTx. This research demonstrates that the one-pot electrodeposition method and the prepared conductive PANI/MXene composite films have potential applications in various fields.
