Solar-driven interfacial water purification and desalination have attracted much attention in environmentally friendly water treatment field. The structure design of the photothermal materials is still a critical factor to improve the evaporation performance such as evaporation rate and energy conversion efficiency. Herein, an asymmetric cellulose/carbon nanotubes membrane was designed as the photothermal membrane via a modified droplet method. Under 1 sun irradiation, the evaporation rate and energy efficiency of pure water can reach up to 1.6 kg m h and 89%, respectively. Moreover, stable reusability and desalination performance made the cellulose/carbon nanotubes membrane a promising photothermal membrane which can be used for solar-driven desalination.
太阳能驱动的界面水净化和脱盐在环境友好型水处理领域备受关注。光热材料的结构设计仍然是提高蒸发性能（如蒸发速率和能量转换效率）的关键因素。在此，通过改进的液滴法设计了一种不对称纤维素/碳纳米管膜作为光热膜。在1个太阳辐照下，纯水的蒸发速率和能量效率分别可达1.6 kg m⁻² h⁻¹和89%。此外，稳定的可重复使用性和脱盐性能使纤维素/碳纳米管膜成为一种有前景的光热膜，可用于太阳能驱动的脱盐。
