Abstract

Polyaniline (PANI) changes its conformation and conductivity on alteration of its electrochemical state. In the present work, we have studied the morphological changes with electrode potential in microtubules and nanowires of PANI using in-situ electrochemical AFM (EC-AFM). About 15 to 20% change in dimensions was observed on changing the electrochemical state in H2SO4 as the electrolyte. Such changes in microtubules and nanowires of PANI may find useful applications in actuation and sensing.
