中文摘要： 随着工业含油废水的大量排放和原油泄漏事故的频繁发生，油水分离成为关系到人民生活、经济发展和环境安全的重要研究领域。为了应对工业废水复杂的酸碱环境和海水的高盐环境，开发稳定、高效、实用的油水分离材料具有重要的研究意义。本项目从仿生设计理念出发，以提高材料环境稳定性与实际应用性为切入点，探索在酸性、碱性和高盐环境下可以稳定使用的超亲水/超疏油型油水分离材料。首先，选用对复杂溶液耐性优良的两性水凝胶材料，通过微/纳米层次的仿生结构设计制备具有稳定超亲水/超疏油性质的表面；进一步，利用以上体系构造双互穿网络，制备具有高强度、自支撑的油水分离材料；在以上研究基础上，加深对超浸润表面用于油水分离机理的探讨，从而进一步指导和优化分离材料的设计与制备。本项目选题围绕民生、环境等国家重点关注领域，针对原油泄漏及工业废水处理等突出环境问题，提出切实可行的油水分离材料设计新方法，具有重要的科学意义和应用前景。

英文摘要： With the increasing industrial oily waste water as well as the frequent oil spill accidents, oil/water separation has become an important field not only for scientific research, but for environmental, economic and social issues. In order to meet practical needs for separation in complex acidic/alkaline environment of industrial waste water and high-salt environment of seawater, it is of great significance to develop stable, efficient, practical materials for oil/water separation. Inspired by nature, we study the preparation and properties of superhydrophilic/superoleophobic materials for stable oil/water separation in acidic, alkaline and high salinity environment. Firstly, by selecting amphoteric hydrogels, which own good tolerance and stable performance for complex solution, we will construct the interface with bio-inspired micro/nanostructures to achieve stable superhydrophilic/superoleophobic surface. Secondly, based on the above study, we will develop high-strength, self-supporting materials for oil/water separation by introduce double network gels. Finally, we will develop and improve the mechanism of superwetting materials for oil/water separation, which would provide insight into the design of new separation materials for different needs. This project presents a new design idea to prepare oil/water separation materials with consideration of both excellent separation ability and environmental stability, which shows attractive potential applications in industrial oily waste water separation and oil spill cleanup.
