 Polystyrene dissolved in a mixture of dimethylformamide and tetrahydrofuran was electrospun to create fibers with submicron diameters. The effects of electrospinning parameters such as solvent combinations, polymer concentrations, applied voltage, and ratios of dimethylformamide and tetrahydrofuran on fiber morphology, tensile strength, and contact angles were investigated. SEM images revealed that a new type of fiber with double-strand morphology was formed when the mass ratio of dimethylformamide and tetrahydrofuran was 50-fiftieths or 25-seventy-fifths. The tensile strength of the PS fiber film was 1.5 mPa, indicating strong reinforcement from double-strand fibers. Bead-free fibers were also obtained by electrospinning 40% with V, PS slash dimethylformamide solution at an applied voltage of 15 kV. When the ratio of dimethylformamide and tetrahydrofuran was 100 slash 0, the maximum contact angle, CA, value. This article was authored by Siki Huang, Guixiang Liu, Guangping Han, and others.
