The effect of electro spinning parameters on polystyrene nano fiber morphology: Oil-water separation

Abstract

This manuscript reports optimized conditions necessary to prepare electro-spun nano fibers and microfibers using two different forms of polystyrene (PS) in dimethylformamide (DMF). We conducted a systematic and methodical study on the influence of all electro spinning parameters to obtain bead-free PS fibers by dissolving the samples in DMF. Polymers with two different molecular weights are used for electro spinning, and they show significant changes on fiber morphology of PS even after maintaining similar electro spinning conditions. After optimizing the parameters, bead-free and uniform PS electro spun fiber mats were prepared and used as efficient, low-cost, and oil-water separator. - 2018 Desalination Publications.
