In Situ Spectroelectrochemical Analysis of Electrochemically Synthesized Conductive Nanocomposites Based on Poly(2-minophenol)/ Titanium Dioxide and Zinc Oxide

In this research, in situ spectroelectrochemistry as a powerful tools for the study and developments of conducting polymerbase nanocomposite materials were introduced. Polymer nanocomposites of 2-aminophenol by in situ electropolymerization and with using nano titanium dioxide and zinc oxide were synthesized and studied on gold (Au) and indium tin oxide glass electrodes (ITO).The poly(2-aminophenol) and 2-aminophenol-titanium dioxide and zinc oxide polymer nanocomposite films were characterized by cyclic voltammetry’s (CVs) method, in situ conductivity measurements (resistivity), in situultra violet-visible (UV-vis.), Fourier transfer infrared (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and energy-dispersive X-ray spectroscopy (EDX). During polymer growth on the electrode surfaces and with in situ electropolymerization method, different behavior and different redox electrode potential values were observed for 2-aminophenol-titanium dioxide and 2-aminophenol zinc oxide polymer nanocomposite films in comparison with poly(2-aminophenol). The same treatments were observed for poly(2-aminophenol) and nanocomposite polymers in blank solutions. In situ spectroelectrochemical properties and in situ conductivity of material products were investigated and compared. Different in situ UV-vis. spectroscopy behaviors were observed for polymer nanocomposites in different the applied electrode potentials which indicated the various optical properties. The results of in situ conductivity of poly(2-aminophenol)in sulfuric acid media and supporting electrolytes at the present of nanoparticles were indicated the improvements of electrical conductivities. Also, the structures and morphological of nano oxide metals in poly(2-aminophenol) films were confirmed by FT-IR spectroscopy, scanning electron microscopy and transmission electron microscopy images. Finally, the presence of nanoparticles in polymer were also confirmed by EDX analysis.
