水下超疏油自清洁TiO_2/CuO纳米结构双层改性铜网膜的制备

Fabrication of Nanostructured Self-cleaning and Underwater Superoleophobic Copper Meshes

膜分离法是一种可高效环保处理含油污水的方法,超亲水及水下超疏油表面在膜分离法处理含油污水中具有抗污染自清洁的作用。本文利用阳极氧化法和层层自组装法制备了TiO_2/CuO纳米结构双层改性铜网膜,对其表面形貌、表面润湿性和光学性能进行了考察,制备的改性铜网具有超亲水-水下超疏油及紫外光照响应的性能。

Membrane separation technology can be used in treatment of oily polluted water with high efficiency and environment protection. The superhydrophilic-underwater superoleophobic surface possesses the properties of anti-pollution and self-cleaning. This paper fabricated bistratal structured TiO2/CuO nanoneedle array（NNA） meshes by anodizing and layer-by-layer process and surface morphology, wettability and optical property were characterized and modified copper meshes were superhydrophilic-underwater superoleophobic and UV responsive.
