Özet

2-Aminothiazole (2AT) was electrochemically polymerized on a Pt electrode using cyclic voltammetry (CV) technique from 0.01 M monomer containing 0.3 M ammonium oxalate solution. The high quality poly-2-aminothiazole (pAT) films with a light-brownish color were obtained on the Pt surface. The electrochemical behavior of the pAT-coated Pt electrode (Pt/pAT) was investigated in monomer-free 0.3 M ammonium oxalate solution by CV technique. The chemical structure characterization was investigated by UV-vis spectroscopy (UV-vis) and Fourier transform infrared spectroscopy (FTIR) techniques. The surface morphology of the polymer film was examined by scanning electron microscopy (SEM) and atomic force microscopy (AFM). The surface morphology studies showed that, a homogeneous and compact film was formed on the Pt surface. Further, thermogravimetric analysis (TGA), differential thermal analysis (DTA) and differential scanning calorimetry (DSC) techniques were used to investigate the thermal properties of the polymer film. It was found that the thermal stability of the pAT film is relatively high. The solubility of the pAT was tested in common organic solvents as well as in acidic and basic solutions.
