This study introduces a method to simultaneously deposit superhydrophilic and underwater superoleophobic properties on the anode and cathode, resulting in materials with superior antifouling capability and excellent oil/water separation efficiency. The fabricated materials also demonstrate outstanding corrosion resistance and maintain high separation efficiency even after 20 cycles.
Superhydrophilic and underwater superoleophobic materials have demonstrated good application prospects in the oil/water separation. However, their fabrication process may be inefficient and high energy consumption. For this reason, this paper proposes a method for simultaneously deposited hierarchical structures with super-hydrophilic and underwater superoleophobic properties on the anode and cathode via one-step electrodeposition. The materials fabricated on both anode and cathode exhibit superior antifouling performance and excellent oil/water separation efficiency (above 96.2% for all five experimental oils) with a considerable permeation flux (4125 +/- 67 L m(-2) h(-1)). Moreover, the as-prepared materials maintain excellent oil/water separation efficiency after 20 separation cycles, which are higher than 98.1% and 98.8%, respectively. Besides, the materials can be stored in different concentrations of salt water for 50 days, demonstrating their outstanding corrosion resistance. Our study provides a strategy for the fabrication of superwetting materials, which is expected to promote the development of oil/water separation technology.
