Abstract

This paper presents the results of polypyrrole nanowires prepared by electrochemical method (Cyclic Voltammograms–CV). The surface morphology structure of polypyrrole nanowires were measured  and analyzed by scanning electronic microscope (FE-SEM). Chemical elements and binding in polymer layer will be analyzed by ultraviolet spectrum (UV-Vis) and infrared spectrum (FT-IR). Polypyrrole nanowires  with a diameter of 5 nm to 50 nm, surface of polypyrrole membrane has the high level of uniformity and porosity very suitable for application in chemical sensors.

Keywords: Polypyrrole, nanowires, Cyclic voltametry.
