A solar steam generation method has been widely investigated as a sustainable to achieve seawater desalination and sewage treatment. However, oil pollutants are usually emitted in real or wastewaters, which can cause serious fouling problems disturb the evaporation performance. In this work, mussel-inspired, low-cost, polydopamine-filled cellulose aerogel (PDA-CA) rationally designed fabricated with both superhydrophilicity underwater superoleophobicity. The resulting PDA-CA device could...
