Aiming to realize the wastewater treatment of various pollutants simultaneously, a dual-functional poly(ether amine)–polydopamine (PEA–PDA)-modified filter material was fabricated in this work for in situ separation of stable oil-in-water emulsion and adsorption of anionic azo dyes. PEA and PDA could be copolymerized via the Michael addition reaction on a polyurethane sponge substrate firmly. The as-prepared filter shows superhydrophilic and underwater superoleophobic wettability. After being squeezed in a glass tube, the material could separate different kinds of stabilized oil-in-water emulsions with high flux and efficiency. Besides, the PEA–PDA copolymer endows the material with the ability to adsorb large amounts of anionic azo dyes during the separation of emulsions with good adsorption capacity. Moreover, adsorbed dyes in the filter material could be easily desorbed in base aqueous solution and the whole process is conducted under gravity without external aid. This dual-functional material shows great potential for the application in industrial field because of its ability for the complex wastewater treatment.

用于废水处理的聚合物装饰滤料：原位超快油/水乳化分离和偶氮染料吸附
为了同时实现多种污染物的废水处理，本研究制备了一种双功能聚醚胺-聚多巴胺（PEA-PDA）改性的滤料，用于原位分离稳定的水包油型乳化液并进行吸附。阴离子偶氮染料。PEA和PDA可以通过迈克尔加成反应牢固地共聚在聚氨酯海绵基材上。所制备的过滤器显示出超亲水性和水下超疏油性的润湿性。在玻璃管中被挤压后，该材料可以高通量和高效率地分离出不同种类的稳定化的水包油型乳液。此外，PEA-PDA共聚物使该材料具有在分离具有良好吸附能力的乳液过程中吸附大量阴离子偶氮染料的能力。而且，过滤材料中吸附的染料很容易在基础水溶液中解吸，整个过程在重力作用下进行，无需外部辅助。这种双功能材料具有处理复杂废水的能力，因此在工业领域具有巨大的应用潜力。
