Abstract :
To prepare uniform nanofibers from poly (ethylene oxide) (PEO), a voltage of 0 to 15 kV was applied to a distance of 15 cm to 30 cm between tip and ground collector. In this study, jet current and Taylor cone were used to express the electrospinning stability. It is showed that an electric current during electrospinning affects the fiber morphology. SEM and jet current monitoring were used to study the jet stability with positive power. It is suggested that it may be concluded that there is a voltage range for spinning with these conditions. The most important one is the Taylor cone shape. When jet current is at the smaller ratio of slope and the Taylor cone still has a part out of the nozzle, the fibers are the most uniform fibers.
