饮水安全与健康是人类面临的重大问题之一，传统的以孔径筛分为分离机理的膜材料难以实现水中微污染物的特异性脱除以及有益物质的保留。针对这一问题，本研究小组近年来持续开展了用于水中微污染物脱除的吸附型分离膜基础研究与关键技术研发，该类膜材料将吸附功能和膜过滤功能结合起来，通过膜中吸附功能基团和微污染物之间的非共价相互作用，可实现水中微污染物的快速脱除。从吸附型分离膜的结构设计角度出发，通过表面凝胶填充、本体填充、原位复合等方法对分离膜进行吸附功能化改性，发展了一系列可用于污染物高效脱除的吸附型分离膜，并赋予膜抗污、抗菌、刺激响应、选择性吸附等多重功能，进一步研究了吸附分离机理，阐述膜结构与分离性能间的相互关系，为发展用于微污染物高效脱除的吸附分离膜提供理论与方法支撑。此外，关于饮用水中微污染脱除的膜材料制备与结构调控研究成果已实现从基础研究到实际应用的转化，所开发的中空纤维膜材料及其净水技术被应用于家用净水设备，已实现规模化生产与应用。

The safety of potable water has become one of the major problems. Traditional membrane separation technology cannot simultaneously remove pollutants in water and retain beneficial substances. In order to solve this problem, our research team has been carrying out basic researches and key technology researches of the adsorptive separation membranes, which combined adsorptive functional materials and filtration membranes. Under the forced convective mass transport, the pollutants were rapidly removed from water via the non-covalent interactions with the adsorption groups, while the beneficial substances can be retained in water. From the perspective of the structural design, this paper reviewed the various construction methods (surface gel filling, bulk filling and in-situ composite) of the adsorptive separation membrane with multiple functions, such as selective adsorption, anti-fouling, antibacterial, stimulus response, etc. Further, the separation mechanism and the relationship between the material structure and separation performance were elaborated, providing theoretical and methodological supports for the development of high-performance adsorptive separation membrane. In addition, the research achievements have been transferred from basic research to practical application. Also the developed hollow fiber membrane materials have been applied to household water purification equipment, and large-scale production and promotion have been realized.
