Wax deposition during the production and transportation of crude oil is a global problem in oil industries. Fabrication of underwater self-cleaning materials can provide a new strategy to prohibit wax deposition. In this paper, conversion films on carbon steel with hierarchical micro/nanostructure are fabricated through a novel in situ alternating-current deposition method. The flower-like conversion films are composed of amorphous iron phosphate and present superhydrophilicity in air and superoleophobicity underwater. The conversion films can efficiently prevent the deposition of wax in water-contained crude oil, showing excellent self-cleaning performance. This facile and low-cost fabrication of a self-cleaning film provides a good strategy for underwater-oil prevention.
在原油的生产和运输过程中，蜡沉积是石油工业中的一个全球性问题。制造水下自清洁材料可以提供一种防止蜡沉积的新策略。本文通过一种新颖的原位交流电沉积方法在碳钢上制备了具有分级微/纳结构的转化膜。花状转化膜由非晶态磷酸铁组成，在空气中呈现超亲水性，在水下呈现超疏油性。转化膜可以有效地防止含蜡原油在水中的沉积，表现出优异的自清洁性能。这种简单且低成本的自清洁膜的制备为水下防油提供了一种很好的策略。
