提出了一种利用疏水性、带电聚合物作为添加剂来调节纳米多孔聚合物膜的润湿性和电荷密度梯度的新策略，以增强水的渗透。本项目所获得的实验结果将促进我们对孔表面电荷和润湿性梯度在水通过纳米孔传输中的作用的基本理解。这项研究有望在设计具有超高通量和优异分离性能的纳米孔膜方面取得重大突破，用于水处理和食品加工等各种应用。

A novel strategy of using a hydrophobic, charged polymer as an additive is proposed to tailor the wettability and charge density gradients in nanoporous polymer membranes for enhancing water permeation. The experimental results obtained in this project will advance our fundamental understanding of the roles of the pore surface charge and wettability gradients in water transport through nanopores. The proposed research is expected to result in a major breakthrough in designing nanoporous membranes with ultrahigh high flux and superior separation properties for a variety of applications including water treatment and food processing.
