Dielectric Response and Electric Modulus Studies of Polythiophene/Reduced Graphene Oxide Nanocomposites

Chemical oxidation reactions were used to create composite materials made of polythiophene (PTh) and reduced graphene oxide with varying compositions. To describe the samples, Fourier transform infrared spectroscopy (FTIR) was used. The hydroxyl (OH) stretching vibrations of the -COOH functional group and adsorbed H 2 O molecules are responsible for the intense bands at 3386 cm -1 and 1302 cm -1 . O-H vibrations can be attributed to absorption at a wavelength of 1610 cm -1 . C-S bending mode of thiophene ring has produced the peak at 666 cm -1 . The dielectric constant, tangent loss, and electric modulus with the applied AC frequency for the polythiophene/reduced graphene oxide composites were studied.
