Özet

Polydiphenylamine was prepared using electrochemical oxidation of the corresponding monomer diphenylamine in an acetonitrile solution containing sodium perchlorate (NaClO4) and characterized spectroscopically. First, some physical characterization using infrared (FTIR) measurement shows that this material has a polymeric structure. Moreover, Differential Scanning Calorimetry (DSC) and thermal gravimetric analysis (TAG) showed a good stability at temperatures above 200 degrees C. Second, the electrical conductivity and dielectric properties of polydiphenylamine were studied as guides for sensing performance using impedance spectroscopy technique in the frequency range 5 Hz-13 MHz at various temperatures (118-150 degrees C).
