Síntesis y caracterización de polipirrol dopado con poliestireno sulfonato de sodio

Abstract

he study of conductive polymers is becoming increasingly important because of the varied and promising properties of these materials. The main objective of this project was to synthesize a conductive polymer, polypyrrole, from solutions of pyrrole monomer and sodium polystyrene sulfonate, to thereby improve the ability of cationic insertion polypyrrole. This synthesis was performed using electrochemical techniques one of which is cyclic voltammetry, in which a variation of potential with time is applied, and the other is chronoamperometry in which a constant potential is applied in a certain amount of time . The characterization of the films obtained was performed using cyclic voltammetry, Impedance Spectroscopy (EIS) and Scanning Electron Microscopy (SEM). sodium polystyrene sulfonate, which showed the ability to experience a cationic doped copper ions - through this process conducting polymer, Polypyrrole was obtained. It is expected that this process will contribute to the management of diseases such as Parkinson building electrodes capable of detecting and quantifying dopamine (a neurotransmitter with specific functions in the central nervous system), in building muscle prostheses, artificial nerves and also in decontaminating ecosystems water.
