Oily wastewater has increasing in recent decades due to industrial production and domestic wastewater. Conventional techniques for oil/water separation such as adsorption, magnetic and combustion suffer from high cost, low efficiency and low regenerability, especially, a large number of oil droplets are embedded in the inner of the membrane, blocking the hole of the membrane so that the membrane cannot be reused. To solve these problems, we synthesized a flower-like visible light driven antifouling membrane, the resultant membrane manifested excellent superhydrophilicity with WCA was 0^° and underwater superoleophobicity with underwater OCA was 158^° More importantly, the developed membrane exhibited a favorable separation efficiency of 99.5% to separate a serious of oil/water mixtures. Remarkably, the membrane presented superior antifouling performance which maintained separation efficiency of 99% under visible driven even after 140 oil/water separations cycles. The avant-garde membrane was investigated in the work hope to become a promising candidate for oil/water separation.

近几十年来，由于工业生产和生活污水，含油废水有所增加。用于油/水分离的常规技术，例如吸附，磁和燃烧，具有成本高，效率低和可再生性低的问题，特别是，大量的油滴嵌入膜的内部，堵塞了膜的孔，因此膜不能重复使用。为了解决这些问题，我们合成了花状可见光驱动的防污膜，所得膜表现出优异的超亲水性，WCA为0 ^°，水下超疏油性为OCA 158 ^°更重要的是，显影后的膜表现出良好的99.5％的分离效率，可分离出大量的油/水混合物。值得注意的是，该膜具有出色的防污性能，即使经过140次油/水分离循环，在可见光驱动下仍可保持99％的分离效率。对前卫膜进行了研究，以期有望成为油/水分离的有前途的候选者。
