“…In recent years, superwetting materials have attracted more and more attention in oil-water separation due to their unique surface waterproof, self-cleaning and lubricating characteristics [6,7]. Inspired by this, super-hydrophobic materials have gained popularity [8]. Oxalic acid and sodium silicate are used to form a hydrophobic surface on the brick to separate the oil in the mixture from the water phase [9].…”

Due to the increasingly serious problem of offshore oil spills, research related to oil–water separation has attracted more and more attention. Here, we prepared a super-hydrophilic/underwater super-oleophobic membrane (hereinafter referred to as BTA) using poly-dopamine (PDA) to adhesive TiO2 nanoparticles on the surface of bacterial cellulose, coated with sodium alienate by vacuum-assisted filtration technique. This demonstrates its excellent underwater super-oleophobic property. Its contact angle is about 153°. Remarkably, BTA has 99% separation efficiency. More importantly, BTA still showed excellent anti-pollution property under ultraviolet light after 20 cycles. BTA has the advantages of low cost, environmentally friendliness and good anti-fouling performance. We believe it can play an important role in dealing with problems related to oily wastewater.
