Sulfonated Fe3O4/PES nanocomposites as efficient separators in microbial fuel cells
In this paper, different self-made membranes based on polyethersulfone (PES) with sulfonated nano-Fe3O4 (Fe3O4-SO3H) were tested in H-Type Microbial Fuel Cell system. The nanomaterials were characterized by FTIR, SEM, TEM and TGA, while the nanocomposite membranes by tensile tests, TGA, SEM, and profilometry. The presence of sulfonic groups (-SO3H) within the polymer matrix allowed a better dispersion of nanoparticles and prevented oxygen permeation from the cathodic compartment.
