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