For obtaining high-throughput production of nanofibers, the preparation mechanism of a self-made spherical section free surface electrospinning (SSFSE) using solution reservoirs with different depths was studied. The effects of the solution reservoir depth on the SSFSE process as well as the quality and yield of polyacrylonitrile (PAN) nanofibers were investigated experimentally using high-speed camera, precise electronic balance and scanning electron microscopy. Furthermore, the results were analyzed theoretically by response surface methodology (RSM) and numerical simulation. The values predicted by the established RSM model and the electric field results obtained by Maxwell 3D were all consistent with the experimental data, which showed that the different depths of the solution reservoir had little effect on the quality of PAN nanofibers, but had great effects on the yields of them. The PAN nanofibers prepared have the best quality and the highest yields when the maximum depth of the solution reservoir was 4.29 mm.

为了获得纳米纤维的高通量生产，研究了使用不同深度的溶液储层的自制球形截面自由表面静电纺丝（SSFSE）的制备机理。使用高速相机、精密电子天平和扫描电子显微镜，通过实验研究了溶液储层深度对 SSFSE 过程以及聚丙烯腈 (PAN) 纳米纤维的质量和产量的影响。此外，通过响应面法（RSM）和数值模拟对结果进行了理论分析。建立的RSM模型预测值和Maxwell 3D得到的电场结果均与实验数据一致，表明溶液储层的不同深度对PAN纳米纤维的质量影响不大，但对它们的产量有很大影响。当溶液库的最大深度为4.29 mm时，制备的PAN纳米纤维质量最好，产量最高。
