Superamphiphobic surfaces, combining both superhydrophobic and superoleophobic properties, show tremendous potential applications in various fields. However, the complicated procedures, expensive equipment, poor mechanical robustness durability seriously limit their commercialization. In this study, superamphiphobic surfaces have been fabricated by a simple spraying method using two different nanostructures of silicon dioxide. The nanosheet silica (about 80 nm) constructed large-scale layer structure, nanospherical 30 interweaved with to form double-scale "reentrant" micronano structure. contact angle (CA) sliding (SA) were estimated be 158° 1° for water droplet, while CA SA measured 154° 3° olive oil, meeting requirement. On other hand, control that only adopted or just satisfy Owing similar chemical components silica, mixed very well uniformly dispersed, endowing whole surface same behavior. More importantly, mixture was sprayed on wet poly(amide-imide) (PAI) substrate, making them easily enter into PAI film. This unique structure is helpful improving durability. Thus, wettability nearly unaffected even though it underwent lots tests, including sandpaper abrasion, ultrasonic treatment, acid–base immersion, UV irradiation, boiling jet impact. As expected, antifouling, self-cleaning, icing delay performances, time prolonged from 55 342 s. It believed robust multifunctions antiliquid-adhesion, anticorrosion, anti-icing enormous industrial environment.
