A 3D hierarchical tree-shaped biomimetic flax fabric is fabricated and modified by one-step synthesis of polydopamine–polypyrrole composite nanofibers to achieve highly efficient solar steam generation, with great potential in water purification and seawater desalination.
Interfacial solar steam generation (ISSG) is considered to be a highly efficient and environmental-friendly desalination technique for producing potable water. Herein, we demonstrate the high-performance SSG enabled by the porous...
