Abstract | CeO2/PPy nanocomposites were synthesized via in situ chemical oxidative polymerization of pyrrole based on the two kinds of amine-functionalized CeO2 nanoparticles with 3-triethoxysilylpropylamine (APTES) or p-aminobenzoic acid (PABA), respectively. The morphology and structure of the CeO2/PPy samples with different interface interactions were comparatively investigated by transmission electron microscopy, Brunauer–Emmett–Teller equation, Fourier transform infrared spectroscopy, UV–vis, X-ray diffraction analysis, X-ray photoelectron spectroscopy, and thermal gravimetric analysis. It was found that the introduction of the amine-functionalized CeO2 nanoparticles into the PPy matrix significantly enhanced the thermal stability and electrical conductivity of the resulting nanocomposites. As an electrode material for electrochemical supercapacitors, the CeO2/PPy nanocomposites with different amine-functionalized CeO2 nanoparticles were characterized by galvanostatic charge/discharge (GCD) and cyclic voltammetry (CV) tests. The CeO2/PPy nanocomposites showed improved electrochemical performance in comparison with the pure PPy. The P-CeO2/PPy nanocomposites synthesized with the PABA-functionalized CeO2 nanoparticles (P-CeO2) exhibited a higher specific capacitance, while those with the APTES-functionalized CeO2 nanoparticles (A-CeO2) possessed the higher cycling stability. |
