Inspired by mussels we designed a novel green superhydrophobic gel nanocoating with good transparency and stability through a facile copolymerization reaction at room temperature and a subsequent trimethyl silyl modified process, which is applicable to various substrates via a simple spray process without requiring toxic substances. Importantly, this well-designed nanocoating has rapid self-healing superhydrophobicity induced by usual organic solvents to face complicated work conditions, which satisfies the need of daily life and can be applied in industry as well.
