Özet

In this study, the polymer was synthesized via template-free oxidative reaction of 3-amino-2-naphthol (AN). For this purpose, bifunctional monomer was polymerized by NaOCl as oxidant in aqueous basic medium to give the corresponding poly (3-amino-2-naphthol) (PAN) with molecular weight ca. 11,100 Da. The chemical and physical properties of PAN were determined by NMR, FT-IR, UV-Vis, gel permeation chromatography (GPC), thermogravimetry (TG), differential scanning calorimetry (DSC), cyclic voltammetry (CV), photoluminescence (PL), dynamic light scattering (DIS), scanning electron microscope (SEM), and transmission electron microscope (TEM). The SEM and TEM analyses indicated to be the resulting polymer has a nanowire structure. The reversible redox behavior of the polymer was attributed to its electroactive nature. In addition, the kinetic parameters related to the solid state decomposition of the polymer were calculated by several methods based on multiple heating rates. (C) 2015 Elsevier Ltd.
