Superhydrophobic polystyrene nanofiber membranes have potential to separate micron scale water droplets from organic due to their hydrophobicity and small pore openings. Polystyrene nanofibers were electrospun into flat sheets and cylindrical filter membranes. The fibers were crosslinked to increase strength and reduce solubility in diesel fuel. The filters were tested and the filtration efficiency was compared to their non-crosslinked counterparts. The optimal electrospinning conditions to create superhydrophobic nanofibers were found to be 20 wt. % PS fibers at 1 mL/hr. under a current of 20kV and at a distance of 20 cm away from the ground. It was found that …
