제목 Preparation of electrospun porous polystyrene fiber by MC/Acetone solvent ratio
초록 The solvent composition ratios of methylene chloride/acetone in polystyrene(PS) solution were proved to be key parameter to affect the fiber surface structure due the various phase separation speeds of the solvents form PS fiber during electrospinning. The concentration of the PS solution is used in the range 10 to 15wt%, and the solvent mixing ratio of methylene chloride/acetone is changed from 90:10 to 40:60. All electrospinning condition was performed by flow rate 100㎕/min, applied voltage 15kV and tip-to-distance(TCD) 10cm. The polystyrene nanofibers were characterized by field emissions scanning electron microscopy(FE-SEM) and Brunauer-Emmett-Teller(BET). The results obtained polystyrene nanofiber having porous surface. Average pore diameter and surface area were about 4.5nm and 63.06 m2/g.
