Preparation method of super-hydrophobic micro-nano zinc oxide copper net

The invention discloses a preparation method of a super-hydrophobic micro-nano zinc oxide copper net. According to the preparation method, a copper net is used as a substrate; a copper net surface with a coarse structure is built by adopting a hydrothermal synthesis method; a low-cost low-surface-energy modifier is used for modification, so that the super-hydrophobic micro-nano zinc oxide copper net is prepared; the preparation method is simple and feasible; furthermore, the used raw materials are small in environmental pollution, low in cost and readily available, and is suitable for large-scale production and application; meanwhile, the super-hydrophobic copper net is relatively high in oil-water separation efficiency and easy to clean and store, can be repeatedly used, and is relatively high in environment stability.
