Research on preparation and properties of pH responsive superhydrophobic coating modified by SEBS

Smart materials with reversible wettability have attracted a lot of attention for application in sewage treatment. In this work, pH-responsive polymer was prepared via the one-step free radical polymerization 3-(trimethoxysilyl) acrylate and 2-dimethylaminoethyl methacrylate. The obtained then coated hydrogenated styrene–ethylene–butadiene–styrene block copolymer to endow material switchable superhydrophilic superhydrophobic properties. Due excellent self-cleaning mechanical stability coating, it used modify paper, which successfully utilized treatment oily wastewater, showing great potential use advanced applications.
