摘要：

Using self-made melt differential electrospinning equipment, using polylactic acid (PLA) as raw material, the influence of melt differential electrospinning auxiliary airflow temperature and spinning distance on fiber diameter, uniformity and pore size distribution was investigated. As the temperature of the airflow rises and the fibers become thinner, the uniformity of the fiber diameter becomes more uniform; the fiber diameter exhibits a trough tendency with the change of the spinning distance; according to the pore size distribution of the fiber membrane, the finer and more uniform the fibers are, the smaller the pore size distribution of the fiber membrane is. The optimal airflow temperature and spinning distance parameters were obtained. The research shows that the spinning temperature is 260℃, the air flow rate is 20 m3/h, the air flow temperature is 100℃ and the spinning distance at 5.5 cm, the average fiber diameter reaches the minimum of about 400 nm. © 2020, Editorial Board of Polymer Materials Science & Engineering.
