摘要：

A superhydrophilic and underwater superoleophobic cellulose graft copolymer/SiO2 coated metal mesh (CASi/ M) was fabricated through a facile and cost-effective process. As-prepared CASi/M could separate different oilwater mixture with a separation efficiency higher than 99.4 % and a flux up to 26940 L.m- 2.h- 1 only driven by gravity. The reusability experiment showed that the separation efficiency still exceeded 99.2 % after 25 cycles, which displayed superior reusability. Furthermore, CASi/M displayed superior stability in corrosive liquids such as acidic, alkaline, and salty environments. This work provides new sights in the development of durable and low-cost functional materials for rapid and efficient oil/water separation.
