A green and template-free electropolymerization of imipramine. The decoration of sponge-like polymer film with gold nanoparticles

Abstract

• Electrochemical polymerization of imipramine. • Comprehensive electrochemical studies of imipramine. • Characterization of modified electrode by FE-SEM, EDX, EDS, AFM, XRD and FT-IR. • Mechanistic studies. • Decoration modified electrode by AuNPs modified electrode. In this study, a green, simple and template-free strategy for the electropolymerization of imipramine is developed. Our data show that the polymerization of imipramine creates an attractive architectures of a sponge-like film on the electrode. The electropolymerization process is performed under template-free conditions without the need for any pretreatment or modification of the underlying surface in water and room temperature. Also, the modified electrode has been decorated by gold-nanoparticles (AuNPs) to improve conductivity of the film. The fabricated electrode has been characterized by the field emission-scanning electron microscopy (FE-SEM), Energy dispersive X-ray spectrometry (EDX), energy dispersive spectroscopy (EDS) mapping, atomic force microscopy (AFM), X-ray diffraction (XRD), and Fourier transform-infrared spectroscopy (FT-IR). The electrochemical performance of the modified electrode is also evaluated by cyclic voltammetry and electrochemical impedance spectroscopy.
