Transparent superhydrophobic surface by silicone oil combustion

Abstract A transparent superhydrophobic coating can be easily created through the use of commercial silicone oil and controlled combustion. In this simple fabrication, silicone oil is sprayed onto a hot glass heated to about 550 °C, resulting in the transparent superhydrophobic coating on the glass. The coating is stable at temperature up to about 450 °C, and against a saline solution and acidic or basic solutions with pH from 4 to 10. This silicone oil-based process does not require any additional solvent, further surface treatment, drying process or post-treatment process. Several applications of this process are exemplified through the proof-of-concept demonstrations.
