Abstract

Abstract : Molecular-scale ordered polyaniline films were produced by coordination crosslinking with Zn ions using a one-step in situ process. Abstract : Considerable research approaches have focused on improving the crystallinity of conducting polymers to enhance the electrical conductivity. However, it is difficult to control the arrangement of polymer chains without the use of expensive and complex methods because of the intrinsic morphology of polymers. Herein, we report a one-step in situ process to produce controlled molecular-scale ordered polyaniline (PANI) films by coordination crosslinking with Zn ions using solvent-vapor thermal annealing (SVTA). The resulting PANI film crosslinked by Zn coordination has a face-centered cubic structure at the molecular scale, which was confirmed by high-voltage electron microscopy. The in situ coordination crosslinking produced a new class of molecular ordering in the PANI films and drastically enhanced their conductivity, showing their potential for use in various electronic and energy devices.
