Intelligent materials with controlled wettability have caused widespread concern in various sewage applications. In this study, a smart pH-responsive polyaniline (PANI) coating has been synthesized in one step in aqueous media and coated on materials in common use, such as polyester mesh, cotton fabric, and sponge. The PANI coatings can switch their superwettability response to ambient pH and be used in continuous separation of oil-water-oil systems which are frequently found in actual oil leakage accidents. Moreover, bidirectional emulsion separation (water-in-oil and oil-in-water) can be realized on such a coating material. The coated sponge can be used as an oil adsorbent for invertible capture and release by changing pH. Based on excellent antifouling and recyclability, as well as the prominent chemical/mechanical stability, PANI coatings can be applied in actual oily wastewater treatment systems. It is anticipated that the coating materials will show promise in many applications because of the cost-effective and environmentally friendly aqueous media preparation procedure.

pH值敏感的聚苯胺超湿涂层：复杂油水混合物的多功能分离。
具有可控制的润湿性的智能材料已引起各种污水应用的广泛关注。在这项研究中，智能的pH响应型聚苯胺（PANI）涂层是在水性介质中一步合成的，并涂覆在常用的材料上，例如聚酯网，棉织物和海绵。PANI涂料可以将其超湿性响应切换至环境pH值，并用于连续分离油水水油系统，这在实际漏油事故中经常发现。此外，可以在这样的涂料上实现双向乳液分离（油包水和水包油）。涂层海绵可用作油吸附剂，可通过改变pH值进行可逆捕获和释放。基于出色的防污性和可回收性以及出色的化学/机械稳定性，PANI涂料可用于实际的含油废水处理系统。可以预见，由于具有成本效益和环境友好的水性介质制备程序，涂料在许多应用中将显示出希望。
