Abstract Solar‐driven interfacial evaporation materials for seawater desalination and wastewater treatment have attracted extensive research interest in recent years. Nevertheless, salt accumulation, costly materials, complex preparation processes greatly hinder the practical application of solar steam generation. Herein, with low‐cost such as carbon black (CB), polystyrene‐b‐polybutadiene‐b‐polystyrene (SBS), commercial cotton fabric, CB@SBS/cotton fabric Janus evaporator is fabricated via a breath figure template (BFT) method scalable, long‐term, stable solar‐driven desalination. The BFT simple yet efficient self‐assembly that endows hydrophobic surface porous structure high light absorption (≈95.5%) escape. As result, can achieve water rate 1.37 kg m –2 h –1 conversion efficiency 91.3% even 3.5 wt% NaCl solution, well stably cycling over 15 times without accumulation (each cycle: 8 illumination 16 rest). work demonstrates an effective strategy achieving high‐performance generation superior rejection capability, which be potentially utilized desalination, sterilization, disinfection.
