In this paper, a study on the synthesis, characterization, and nanofiber preparation of a hydroquinone-based sulfonated polysulfone was conducted. The sulfonated monomer was synthesized by electrophilic substitution. Then, a polycondensation reaction was applied to prepare the polymer with a 40% degree of sulfonation. A chain extender strategy was used for the synthesis of the polymer. Fourier transform infrared and nuclear magnetic resonance spectroscopy techniques were used to characterize the synthesized monomer and the polymer. In the following, for preparation of bead-free homogeneous electrospun nanofibers, the electrospinning parameters including polymer solution concentration, voltage, flow rate, and needle to collector distance were challenged. Taguchi design of experiments was used to determine process variables to save time and cost. Then, according to the scanning electron microscopy images, the optimum conditions were determined. The Genetic algorithm was used to find the optimum condition. Also, the effect of process variables on morphology and formation of nanofibers was studied.
