水中新兴有机污染物，特别是PPCP引发的生态和健康安全问题日益突出。前期研究发现碳纳米复合膜的吸附过滤功能能有效去除水体中的PPCP，但碳纳米复合膜单纯的吸附过滤功能需借助外界压力完成。组合光热材料与碳纳米材料，制备兼具光热功能和吸附过滤功能的光热膜，一方面上升的水蒸汽可以提高污染物的去除效率，同时可以通过热蒸发实现清洁水回收。但该技术的应用研究仍不够完善，在材料制备和去除效果等领域仍有待进一步研究。.本项目针对光热复合膜结构制备的不可控、膜结构与小分子PPCP去除的构效关系以及去除机制尚不明确的问题，采用材料制备-去除机制-效果优化为贯通式研究，优化3D光热复合膜制备并考察其对典型PPCP的去除效果。结合宏观和微观尺度的表征，通过密度泛函理论计算模型，解析构效关系和去除机制，优化复合膜的制备以期实现光热膜的可控制备及其对PPCP去除机理的挖掘，为新型膜法深度水处理技术的应用奠定基础。

The increased discharge of emerging contaminants, especially for pharmaceutical and personal care products (PPCP), into the water system contributes to a series of environmental problems. Therefore, developing novel and advanced water treatment methods are in demand to realize PPCP removal and efficient water purification to ensure human health. Our previous studies demonstrate that carbon nanocomposite membranes are efficient for PPCP removal in water bodies, while the prepared nanocomposite membranes filtration should be operated under pumping pressure with the single function of adsorption filtration. The photothermal composite membranes prepared by the combination of carbon nanomaterials and photothermal materials, not only increase the PPCP removal by the evaperation-enhanced adsorption, but also efficiently realize water regeneration via thermal evaporation. However, the uncontrolled membrane structure, the unclear structure-activity relationship between membrane structure and PPCP removal, as well as the vague underlying mechanisms for PPCP removal. .To solve the above problems, consecutive study of Material-Mechanism-Optimization is adopted in this project, to optimize the 3D printing of photothermal membrane and their application on PPCP removal. Experimental results in combination with theoretical calculations will be analyzed to reveal the underlying structure-activity relationship of the photothermal membranes. The findings of this project is desired to realize the controlled preparation of photothermal membrane, clarify the underlying PPCP removal mechanism, laying the foundation of multifunctional photothermal composite membrane technology for the development of advanced water treatment.
