We study the impact of the induced pressure fields on the water flow and salt rejection in nanopores produced in MoS membranes. We observe that the water permeability and the salt rejection are not impacted by the distance between the pores. This result contradicts the continuous fluid mechanics calculations in microfilters, which indicates the existence of hydrodynamic interactions between adjacent pores that increase the water mobility. Our results suggest that at this nanoscale, the hydrodynamic interactions do not affect the water mobility through nanopores.
我们研究了诱导压力场对二硫化钼（MoS）膜中纳米孔内水流和盐分截留的影响。我们观察到，水渗透率和盐分截留不受孔间距的影响。这一结果与微滤器中的连续流体力学计算结果相矛盾，后者表明相邻孔之间存在流体动力相互作用，这种相互作用会增加水的流动性。我们的结果表明，在这种纳米尺度下，流体动力相互作用不会影响水通过纳米孔的流动性。
