Abstract

As an emerging research direction, advanced membranes with responsive two-dimensional (2D) nanochannels are developed to mimic biological functions of cell membranes. Tuning the physical and/or chemical properties of the interfaces of nanochannel walls, the mass transport in the artificial 2D channels can be easily managed, analogous to the proteins in the cell membranes that interact specifically with chemical species and adjust conformation responsively adapting to their environments. Such artificial membranes that could regulate their permeability and/or selectivity correspondingly in response to the environmental signals are of particular importance. This review summarizes the recent developments in the functional membranes with responsive 2D nanochannels including the design strategies, stimuli-responsiveness of the nanochannels and the advanced applications of membranes with responsive 2D nanochannels in water purification, molecular separation, energy harvesting and so on. The functional membranes with responsive 2D nanochannels, which are featured with intrinsic intelligence, show great power for use in global sustainable development.

具有响应性二维纳米通道的先进膜

具有响应性二维纳米通道的先进膜是一个新兴的研究方向，它可以模拟细胞膜的生物功能。调整纳米通道壁界面的物理和/或化学性质，可以很容易地管理人工二维通道中的质量传输，类似于细胞膜中的蛋白质与化学物质特异性相互作用，并响应地调整构象以适应其环境。这种能够根据环境信号相应地调节其渗透性和/或选择性的人造膜特别重要。本文综述了响应性二维纳米通道功能膜的研究进展，包括响应性二维纳米通道的设计策略、刺激响应性及其在水净化、分子分离、能量收集等方面的先进应用。具有响应性的二维纳米通道功能膜具有内在智能的特点，在全球可持续发展中显示出巨大的应用潜力。
