A fluorine-free and transparent superhydrophobic coating was fabricated via a simple method. The coated glass exhibited excellent superhydrophobicity with water contact angle (WCA) about 156 degrees and sliding angle (SA) about 3 degrees. In addition, the as-prepared superhydrophobic glass also showed great transparency and self-cleaning properties. The superhydrophobic polydopamine@SiO₂ (PDA@SiO₂) coating can be also applied on other substrate surfaces through a spray-coating approach. Moreover, a sponge coated by the superhydrophobic coating can be used to absorb oil from water.
