摘要：
A series of water-soluble polymers such as poly(ethylene oxide)(PEO), polyacrylamide(PAM) and poly(vinyl pyrrilidone)(PVP) was successfully prepared via the electrospinning of their aqueous solutions without the use of a surfactant. The effects of solution properties on the electrospinning of PEO, PAM and PVP solutions were investigated. The viscosity of the solution, charge density carried by the jet, and the surface tension of the solution are the key factors that influence the morphology and diameter size of the fibers. The viscosity of the solution was measured on a modular compact rheometer. The morphology and the diameter size distribution of the fibers were observed under an environmental scanning electron microscope(ESEM). The results show that the diameters of the nanofibers electrospun from the solutions of these water soluble polymers were uniform and less than 300 nm.
