Solar-driven interfacial evaporation (SIE) is a promising avenue for clean water production, but its widespread application is hindered by challenges such as surface water contamination and the corrosive nature of oily wastewater. In this study, we introduce a novel approach to mitigate these issues by developing a cotton fabric coated with carbon black nanoparticles and calcium alginate hydrogel (CCCF). This coating imparts the fabric with remarkable properties, including strong light absorption, superhydrophilicity, and underwater superoleophobicity. These characteristics enable the CCCF-based evaporator to achieve an impressive water evaporation rate of 1.44 kg m⁻² h⁻¹ under one sun, even in the presence of various oil contaminants. Furthermore, the CCCF exhibits outstanding reusability and stability under harsh environmental conditions, including exposure to acidic, alkaline, and saline environments, as well as elevated temperature. These findings highlight the potential of CCCF as a practical and scalable solution for fabricating SIE systems with enhanced efficiency and durability. Our research represents a significant step forward in the development of sustainable water production technologies for diverse environmental conditions.

可扩展且环保的防油污太阳能界面蒸发器制造，可实现高效水净化


太阳能驱动的界面蒸发（SIE）是一种很有前景的清洁水生产途径，但其广泛应用受到地表水污染和含油废水腐蚀性等挑战的阻碍。在这项研究中，我们引入了一种新方法来缓解这些问题，即开发一种涂有炭黑纳米粒子和海藻酸钙水凝胶（CCCF）的棉织物。这种涂层赋予织物卓越的性能，包括强吸光性、超亲水性和水下超疏油性。这些特性使基于 CCCF 的蒸发器能够在一个太阳下实现 1.44 kg m ⁻² h ⁻¹ 的令人印象深刻的水蒸发率，即使存在各种油污染物。此外，CCCF在恶劣的环境条件下表现出出色的可重复使用性和稳定性，包括暴露于酸性、碱性和盐水环境以及高温。这些发现凸显了 CCCF 作为实用且可扩展的解决方案的潜力，可用于制造具有更高效率和耐用性的 SIE 系统。我们的研究代表了针对不同环境条件的可持续水生产技术的开发向前迈出了重要一步。
