The superamphiphobicity includes extremely nonwetting phenomena of superhydrophobicity and superoleophobicity. Superoleophobicity is relatively harder to realize but has a lot of promising applications. The biomimetic methods are usually adopted to acquire superoleophobic materials, including building up rough structures and modifying materials with low surface energy on surfaces. The rough structures are easy to be destroyed by mechanical effects such as friction and impact, since many situations of using superoleophobic materials involve the gear friction and bearing transmission. The low surface energy materials tend to decompose under UV irradiation, however, a range of solar devices which include solar panels have to work outdoor. Superoleophobicity with UV resistance applied on these devices helps to prolong service life while maintaining the working effiency, which can save energy and fulfill eco-friendly industry. For solving these problems, researchers study reliability of superoleophobic materials under different kinds of harsh circumstances. This review summarizes the latest advances on the reliable performances of superoleophobic material under ultraviolet irradiation; repeated impact, high temperature, and other complicated conditions. Because most of industrial environments accompanied with corrosion and friction, this review sets an emphasis on superoleophobic materials' anticorrosion and friction resistance properties. In the end, we summarize the drawbacks and advantages of plentiful experiments, the problems of products, the promising breakthrough, and the standpoints about how to improve superoleophobic materials' performance and stability under the harsh operating conditions.
