Effect of LiCl on Electrospinning of Polyvinylalcohol and Polyacrylonitrile Solutions
Electrospinning is an effective method to produce fibers with sub-micro diameter. In this work, polyvinylalcohol (PVA) and polyacrylonitrile (PAN) solutions with the different content of LiCl were used to preparing electrospun fibers. The effects of ionic salt on jet thinning, and the structure and morphology of electrospun fibers were investigated by optical microscopy, Wide-angle X-ray diffraction (WAXD) and scanning electron microscopy (SEM). The result showed that LiCl exhibited obvious impact on jet thinning beyorid the onset of bending instability during electrospinning, and with increasing the content of LiCl in solution, the crystalline size of electrospun fibers decreased. Although impact of the content of LiCl in solution on fiber diameter distribution is significant, polymer solution concentration played a more important role on bead formation and fiber diameter.
