采用阳极氧化和阴极沉积相结合的方法制备了一种新型的一体化丝网结构，实现了油水的智能双重选择性分离。由于油和水的输送方向不同，采用特制的装置可以实现油水混合物的完全分离。挤出压力作为一个临界压力，取决于液体表面张力，基板微观结构和润湿性能，可以是一个主要因素，以确定通过或阻塞模式。这种一体化丝网具有良好的油水分离性能，在流体精馏、微化学反应控制、高级分离、生物医用材料、工业废水净化等方面具有广阔的应用前景。
Smart dual selective water/oil separation mode appears on an integrative mesh, which is fabricated via combined anodic oxidation and cathodic electrode-deposition methods. Due to the different transport directions of oil and water, oil-water mixture can be separated completely using tailor-made device. Extrusion pressure, acting as a critical pressure that depends on liquid surface tension, substrate microstructures, and wetting properties, canbe a major factor to determine the passing or blocking mode. These remarkable water/oil separation properties of the integrative mesh can bring about novel applications in fluid rectifying, microchemical reaction manipulation, advanced separation, biomedical materials, purifying industrial wastewater, etc.
