DEVELOPMENT OF CONDUCTIVE POLYMER NANOFIBER OBTAINED BY ELECTROSPINNING FOR APPLICATION IN SENSORS AND HETEROJUNCTION

Abstract

The purpose of this project is to develop nanofiber arrays of insulating polymers (IMs), PVDF, PMMA and PVA, functionalized with intrinsically conductive polymers (ICPs), polyaniline, PPy and PEDOT, targeting an application as sensors of gases ammonia (NH3) carbon monoxide (CO) and hydrogen cyanide (HCN). It will also be performed to study the interaction of MI cited for fullerene derivative (PCBM) in use in heterojunction organic photovoltaic devices (OPVs) determining what concentration and matrix which is most suitable for production of nanofibres MI / PCBM. Initially there will be a study of the percolation threshold of the conductive polymer (ICP) and PCBM the insulating matrix (MI), then an investigation of the optimal parameters for electrospinning to define and ensure reproducibility of homogeneous nanofibers with minimal possible diameter, analyzed by the characterization techniques: spectroscopy MicroRaman, ultraviolet UV-Vis, scanning electron microscopy (SEM); and favorable conductive properties, investigated by electrical measurements AC / DC.
