Efficient superhydrophobic oil-water separation materials are essential for environmental remediation and industrial wastewater treatment. In this study, by optimizing printing parameters, such as printing speed, extrusion multiplier, and layer height, we achieved high-precision 3D porous architectures with uniform pore sizes. The pore size could reach 677.3 µm, with a maximum deviation of less than 36.1 µm. Additionally, we successfully printed pores as small as 186.7 µm, representing the smallest FFF-printed pore size reported in the literature. The printed structures were modified using a spray-coating method, achieving a superhydrophobic surface with a water contact angle of 158.2°. The material was tested in a continuous oil-water separation system, maintaining stable oil removal performance for 24 h. The highest separation efficiency reached 88.6%, demonstrating strong durability and long-term applicability. This study establishes a scalable, low-cost approach for fabricating highly efficient 3D superhydrophobic porous materials, offering new opportunities for continuous oil spill cleanup and industrial wastewater treatment.
高效的超疏水油水分离材料对于环境修复和工业废水处理至关重要。在本研究中，通过优化打印参数，如打印速度、挤出倍率和层高，我们实现了具有均匀孔径的高精度三维多孔结构。孔径可达677.3 µm，最大偏差小于36.1 µm。此外，我们成功打印出了小至186.7 µm的孔隙，这是文献报道中最小的熔融沉积成型打印孔径。使用喷涂方法对打印结构进行改性，获得了水接触角为158.2°的超疏水表面。该材料在连续油水分离系统中进行了测试，在24小时内保持了稳定的除油性能。最高分离效率达到88.6%，显示出强大的耐久性和长期适用性。本研究建立了一种可扩展、低成本的方法来制造高效的三维超疏水多孔材料，为持续的溢油清理和工业废水处理提供了新的机遇。
