Ceria nanoparticles were added to PBI membranes as free-radical scavengers to minimize the degradation of the polymer bulk. The 7nm Ceria nanoparticles were synthesized by combustion synthesis and the crystal structure was characterized by X-ray powder diffraction (XRD) and TEM. The oxidative degradation of PBI and PBI-CeO2 membranes was studied under the Fenton test conditions by the weight loss,...
