内容摘要：We report onthe preparation and characterization of core–sheath structure of compositenanofibers by using electrospinning process. The morphology, chemicalcompositions, structure and thermal properties of the resultant products werecharacterized by scanning electron microscopy (SEM), energy dispersive X-rayspectrometer (EDX), high-resolution transmission electron microscopy (HR-TEM),Fourier transform infrared (FT-IR) spectroscopy, differential scanningcalorimetry, thermogravimetric analysis (TGA) and X-ray photoelectronspectroscopy (XPS) techniques. The blending ratio of Core polymer and Sheathpolymer, molecular weight of polymer and the applied voltage of electrospinningprocess were observed to be the key influence factors on the formation ofcore–sheath nanofibers structure. Bicomponent nanofibers increases the weightand strength than the single-component fibers. Therefore, It can be applied theseparation, sensors, catalyst, bio, electronic devices, etc to various fields.
