In the present study, the influence of the electrical parameters of the pulsed electrospinning process, such as the electrical voltage, the frequency of pulses, and the pulse duration, on the structure of obtained nonwovens was determined for the first time. It was found that all the parameters studied strongly influence the average diameter of the obtained fibers and that the pulsed electrospinning process carried out under specific conditions makes it possible to obtain, among other things, bimodal nonwovens. A 2 factorial design was used to determine how the selected electrical parameters of the pulsed electrospinning process affect the structure of the resulting electrospun mats. It is shown, among other things, that by appropriately selecting the parameters of the electrospinning process, the thickness of fibers can be controlled, resulting in nonwovens with a desired morphology.
在本研究中，首次确定了脉冲电纺丝过程的电学参数，如电压、脉冲频率和脉冲持续时间，对所得非织造布结构的影响。研究发现，所有研究参数都对所得纤维的平均直径有强烈影响，并且在特定条件下进行的脉冲电纺丝过程能够获得双峰非织造布等。采用二因素设计来确定脉冲电纺丝过程中选定的电学参数如何影响所得电纺垫的结构。研究表明，除其他外，通过适当选择电纺丝过程的参数，可以控制纤维的厚度，从而得到具有所需形态的非织造布。
