Polyaniline doping with nanoparticles: A review on the potential of electrical properties

Abstract

Abstract During this decade, there is a growing interest of the conducting polymers owing to their exceptional and outstanding electrical properties which makes them potentially applicable in a wide range such as electrochromic displays electronic devices, modified electrodes, chemical and bio-sensors. Here we aimed to examine the reported polyaniline doping (PANI) with graphene oxide (GO) and carbon nanotubes (CNT) by insitu polymerization. The molecular structure of PANI and its composites was characterized using FTIR, X-ray diffraction and their morphologies described by scanning electron microscopy (SEM). Previous results showed that the strength of composite peaks was higher than pure PANI due to charge transfer between PANI and graphic allotropes, and the aniline molecules have been physically adsorbed and polymerized on the surface of GO and CNT due to the interaction of p – p * electron. PANI describes a multi-diameter external layer of composites depending on the PANI degree of deposition, where the core GO and CNT participate. The conductivity calculation explained that 0.1 wt % of PANI with CO matrix has conductivity 17 folds higher than that without GO.
