Abstract: In order to solve the problem of needle blocking and hard industrialization of traditional needle-type electrospinning, the PVA nanofibers was spun by using the copper wire dynamic linear electrode electrospinning technique. The influences of PVA solution concentration, voltage and spinning distance on the morphology and diameter distribution of PVA nanofibers were studied by scanning electron microscopy (SEM). The results showed that, when PVA solution concentration decreased, solution viscosity and conductivity decreased, fiber diameter and its distribution became narrow. With the increase in spinning distance, the fiber diameter became smaller, and the fiber morphology became better. When the PVA concentration was 10wt%, the voltage was 80 kV and the distance was 30 cm, the nanofibers had good morphology, the diameter was 433 nm, and the yield reached 6.8 g/h. When the PVA concentration was 5wt%, the voltage was 80 kV, distance was 30 cm, the smallest diameter of spinning fibers reached 96 nm. This study can provide a reference for the future large-scale preparation of PVA electrospun nanofibers.
