This document discusses the preparation and characterization of sulfonated polystyrene films using electrospinning. Sulfonated polystyrene fibers were created by electrospinning a solution of polystyrene in dimethylformamide, then immersing the films in sulfuric acid to introduce sulfonate groups. Fourier transform infrared spectroscopy showed peaks indicating successful sulfonation. Scanning electron microscopy with energy-dispersive X-ray spectroscopy revealed the films
