Fabricating amphiphobic surfaces is often complex, difficult to control, and time-consuming, making the fabrication process very difficult. Herein, a facile and time-saving modification method using a mixed modified solution of stearic acid and perfluorooctanoic acid was initially proposed, which played a key role in the achievement of the superhydrophobicity and highly oleophobicity. The effects of reaction time on surface morphology and wettability as well as the content of perfluorooctanoic acid in the mixed modified solution on wettability were investigated to determine the optimal experiment parameters that maximized the amphiphobicity of the surfaces. The as-fabricated amphiphobic surfaces displayed high oil contact angles of 133.5°, higher water contact angles of 156.8°, ultra-low water sliding angles of less than 5° and excellent self-cleaning properties. The facile, easy to control, and efficient method can provide new insights into fabricating amphiphobic surfaces and can open up a new way for the basic research and practical application of amphiphobic surfaces.
制备两疏表面通常很复杂，难以控制且耗时，这使得制备过程非常困难。在此，首次提出了一种使用硬脂酸和全氟辛酸混合改性溶液的简便且省时的改性方法，该方法在实现超疏水性和高疏油性方面发挥了关键作用。研究了反应时间对表面形貌和润湿性的影响以及混合改性溶液中全氟辛酸含量对润湿性的影响，以确定使表面两疏性最大化的最佳实验参数。所制备的两疏表面显示出133.5°的高油接触角、156.8°的更高水接触角、小于5°的超低水滑动角以及优异的自清洁性能。这种简便、易于控制且高效的方法可为两疏表面的制备提供新的见解，并可为两疏表面的基础研究和实际应用开辟一条新途径。
