Water transport through a disjoint nanochannel is important for understanding water molecules confined in a complex nanostructure. However, the transport behavior of water molecules in the disjoint nanochannel is affected by the nanogap of the disjoint nanochannel greatly. It is still difficult to transfer water molecules through the disjoint nanochannel with a large nanogap even under high pressure. In this article, we report water transfer properties through a disjoint nanochannel with a large nanogap under the influence of an electric field. By the aid of the electric field, the efficiency of water transfer through a (10, 0) disjoint nanochannel is enhanced sharply. The transfer of water molecules through a (12, 0) disjoint nanochannel and a (14, 0) disjoint nanochannel increases under an appropriate electric field but decreases under a strong electric field. Our findings are beneficial to achieve a stable and fast water transport through a disjoint nanochannel.

通过不相交的纳米通道的水传输对于理解限制在复杂纳米结构中的水分子很重要。然而，分离纳米通道中水分子的传输行为受分离纳米通道纳米间隙的影响很大。即使在高压下，水分子仍然难以通过具有大纳米间隙的不相交纳米通道转移。在本文中，我们报告了在电场影响下通过具有大纳米间隙的不相交纳米通道的水传输特性。在电场的帮助下，水通过 (10, 0) 不相交的纳米通道的传输效率急剧提高。水分子通过 (12, 0) 不相交的纳米通道和 (14, 0) 不相交的纳米通道在适当的电场下增加，但在强电场下减少。我们的发现有利于通过不相交的纳米通道实现稳定和快速的水传输。
