太阳能蒸汽发电正在成为利用丰富的绿色太阳能收集清洁水的最重要的可持续技术之一。如何合理设计太阳能蒸发器，实现高性能的太阳能蒸发成为一个重大的挑战。在这里，一个多孔太阳能蒸发器与光热公约，水传输和热管理的综合优化开发使用有吸引力的皮克林乳液凝胶（APEG）为模板，然后在分子尺度上的界面工程。APEG-TPE是一种导热系数为0.039 W·m−1·K−1的固有绝热材料。水解后，内表面上的叔丁基基团转化为羧酸基团，使内表面亲水并促进水通过互连孔的传输。聚吡咯层的引入赋予了多孔材料~ 97%的高光吸收，这可以有效地将太阳辐射转化为热量。由于APEG系统的多功能性，APEG-TPE的组成、压缩模量、孔隙率可以很好地控制，并且在模拟太阳辐照下实现了69%的高太阳能蒸发效率，蒸发速率为1.1 kg·m-2·h-1。界面设计的APEG-TPE在清洁水收集方面很有前途，可以激发太阳能蒸发器的未来发展。
Solar vapor generation is emerging as one of the most important sustainable techniques for harvesting clean water using abundant and green solar energy. The rational design of solar evaporators to realize high solar evaporation performances has become a great challenge. Here, a porous solar evaporator with integrative optimization of photothermal convention, water transport and thermal management is developed using attractive Pickering emulsions gels (APEG) as templated and followed by interfacial engineering on a molecular scale. The APEG-templated porous evaporators (APEG-TPEs) are intrinsically thermal insulation materials with a thermal conductivity = 0.039 W·m−1·K−1. After hydrolysis, t-butyl groups on the inner-surface are transformed to carboxylic acid groups, making the inner-surface hydrophilic and facilitating water transport through the inter-connected pores. The introduction of polypyrrole layer endows the porous materials with a high light absorption of ~97%, which could effectively convert solar irradiation to heat. Due to the versatility of the APEG systems, the composition, compressive modulus, porosity of APEG-TPEs could be well controlled and a high solar evaporation efficiency of 69% with an evaporation rate of 1.1 kg·m−2·h−1 is achieved under simulated solar irradiation. The interface-engineered APEG-TPEs are promising in clean water harvesting and could inspire the future development of solar evaporators.
