WebJun 8, 2024 · Herein, with low-cost materials such as carbon black (CB), polystyrene-b-polybutadiene-b-polystyrene (SBS), and commercial cotton fabric, the CB@SBS/cotton fabric Janus evaporator is fabricated via a breath figure template (BFT) method for scalable, long-term, and stable solar-driven interfacial desalination. Breath-figure self-assembly is the self-assembly process of formation of honeycomb micro-scaled polymer patterns by the condensation of water droplets. "Breath-figure" refers to the fog that forms when water vapor contacts a cold surface. In the modern era systematic study of the process of breath-figures water condensation was carried out by Aitken and Rayleigh, among oth…
