Abstract
Polyacrylonitrile (PAN)/ Polyethyleneglycol (PEG) blend nanofibers were prepared by electrospinning blend solutions of PEG and PAN in N, N-dimethylformamide (DMF). The surface morphology, thermal properties and crystal structure of electrospun PAN/PEG nanofibers were characterized using Fourier transform infrared spectroscopy (FT-IR), wide-angle x-ray diffraction (WAXD), scanning electron microscopy (SEM), Thermo gravimetric analyses (TGA) and differential scanning calorimetry (DSC). SEM image showed that the scope of the diameters was 320-480nm. The diameters of the blend fibers decreased with the increasing of PEG content. FT-IR indicated that intermolecular interactions are formed between two different polymers, which influence the thermal and crystalline properties of electrospun blend nanofibers..
