Electrospray-assisted interfacial polymerization has recently raised researchers’ attention during membrane fabrication process due to the thickness of the polyamide layer is tunable in nanometers. Here we report that 2D molybdenum disulfide (MoS₂) nanosheets could endow the electrospray-assisted interfacial polymerization polyamide membrane with improved selectivity at a short spray time. The nanosheets dispersed uniformly under the electric field. The optimal TFN-15 membrane demonstrated water permeance of 9.23 L m⁻² h⁻¹·bar⁻¹ and Na₂SO₄ rejection of 95.4%. Furthermore, the obtained polyamide membranes showed splendid stability and antifouling. Our research provides an effective strategy for the optimization of the fabrication process of the electrospray-assisted interfacial polymerization polyamide membrane with high-performance.

电喷雾辅助界面聚合最近引起了研究人员在膜制造过程中的关注，因为聚酰胺层的厚度可以在纳米范围内调节。在这里，我们报告了二维二硫化钼 (MoS ₂ ) 纳米片可以在短喷雾时间内赋予电喷雾辅助界面聚合聚酰胺膜更高的选择性。纳米片在电场下均匀分散。最佳TFN-15膜的透水性为9.23 L m ^-2  h ^-1 ·bar ^-1和Na ₂ SO ₄拒绝率 95.4%。此外，得到的聚酰胺膜表现出优异的稳定性和防污性。我们的研究为优化电喷雾辅助界面聚合高性能聚酰胺膜的制备工艺提供了有效的策略。
