In this work, a new hydrophobic membrane with nanofibrous structure was prepared from polystyrene using the electroblowing technique, for the first time, for desalination experiments. Using this technique, the injection rate for the dope solution increased up to 117 µL/min. This means faster and considerably higher fiber productivity as compared to the typical electrospinning. The membrane was treated via a hot-press post treatment. The new membrane was analyzed for the surface morphology and topography, and was then evaluated for desalination using DCMD process. The results for the new membrane compared to a commercial PTFE membrane with 0.22 µm pore size. Larger mean pore size (0.562 µm) was observed for the new membrane. However, the membrane porosity for the nanofibrous membrane was comparable with the PTFE one (∼75%). The fabricated membrane was thinner and therefore it produced higher permeate flux. Both fabricated and commercial membranes showed ˃99% salt rejections for lower range of feed flow rate (≤0.48 L/m). Most importantly, the new membrane fabricated using a cheap and available polymer via a fast technique for DCMD desalination. The hot-pressed, nanofibrous membrane showed higher surface hydrophobicity (154.52^o) than the commercial membrane (124.61^o). The superhydrophobic state of the new membrane prevented the liquid encroachment into the membrane pores. This consequently improved not only the permeate flux, but also the average salt rejection. Overall, the new fabricated membrane showed a reasonable desalination performance.

在这项工作中，首次使用电吹技术由聚苯乙烯制备了一种具有纳米纤维结构的新型疏水膜，用于脱盐实验。使用该技术，涂料溶液的注入速率提高到117 µL / min。与典型的静电纺丝相比，这意味着更快，更高的纤维生产率。膜通过热压后处理进行处理。分析新膜的表面形态和形貌，然后使用DCMD工艺评估其脱盐性能。与孔径为0.22 µm的商用PTFE膜相比，该新型膜的结果。新膜的平均孔径较大（0.562 µm）。但是，纳米纤维膜的膜孔隙率与PTFE膜的孔隙率相当（〜75％）。制成的膜更薄，因此产生了更高的渗透通量。对于较低的进料流速范围（≤0.48L / m），人造膜和商用膜均显示出˃99％的脱盐率。最重要的是，这种新型膜是通过廉价的可用聚合物通过快速的DCMD脱盐技术制成的。热压的纳米纤维膜表现出更高的表面疏水性（154.52^o）比商用膜（124.61 ^o）。新膜的超疏水状态阻止了液体侵入膜孔中。因此，这不仅提高了渗透通量，而且还提高了平均脱盐率。总体而言，新制造的膜显示出合理的脱盐性能。
