Abstract
A novel poly(1,4-diaminonaphthalene) was synthesized from the monomer 1,4-diaminonaphthalene at the nanoscale via an oxidative polymerization method. The reaction was conducted in an acidic (HCl) medium under an ultrasound homogenizer at 0 °C, while potassium persulfate was used as a radical initiator. This polymer has been characterized using various techniques, including FTIR, UV-Vis spectroscopy, thermogravimetric analysis (TGA), scanning electron microscopy (SEM), NMR analysis, and electron paramagnetic resonance (EPR) methods. The nanopolymers were found to be thermally stable up to 200 °C. EPR data further substantiated the presence of unpaired electrons on the nitrogen atoms within the polymer backbone.
