A blending nanofibrous mats comprising polystyrene(PS) and polyvinylacetate (PVAc) were prepared by electrospinning. All electrospinning condition was performed with MC/EtOH(80/20,v/v) solvent system at flow rate 100 ㎕/min, applied voltage 15 kV and tip-to-distance(TCD) 10 cm. The weight ratios of PS/PVAc blended polymer solution affect on the number of jets of PS/PVAc. The nanofibrous mats were characterized by field emission scanning electron microscopy(FE-SEM) and Fourier transform infrared(FT-IR) spectroscopy, differential scanning calorimeter(DSC) and (Thermogravimetric analysis(TGA). |
