Abstract

Innovative hybrid composites of poly 4, 4′-diaminodiphenyl sulfone (PDDS)-zirconium dioxide (ZrO 2 )/cerium dioxide (CeO 2 ) were prepared using a chemical polymerization process. The functional groups were analyzed using Fourier transform infrared spectroscopy profiles that revealed polymer establishment through N[sbnd]H group stretching and in-plane bending vibrations about ∼3454 and ∼1623 cm −1 , respectively. Scanning electron microscopy and transmission electron microscopy images were used to explore the morphology of nano-sized grains in the hybrid composites. The improved electrochemical capacitance behavior was confirmed by cyclic voltammetry curves. Charge-discharge curves were used to determine capacitance values of 229 and 288 F·g −1 for PDDS-ZrO 2 (15 wt%) and PDDS-CeO 2 (15 wt%) nanocomposites, respectively.
