目前，太阳能驱动的气液界面蒸发主要集中在提高太阳光吸收效率，而忽略了水分输运的调节。盲目追求超湿材料设计忽视了使用过量的水输送，而增加了不必要的热损失。此外，还应关注材料的生物安全性，以避免在应用过程中对水源生物和人体造成损害。在这里，我们成功地设计了一个生物安全的乌贼汁（CJ）为基础的太阳能吸收器通过旋转填充二氧化硅纳米粒子（NPs），以优化SGIE系统的水传输调节，量身定制的吸收器可以阻止多余的无用的水，并有效地减少热损失。因此，该吸收剂具有特定和显著的优点：更高的蒸发效率和对整个装置的快速蒸发响应，优异的生物相容性和低毒性，在细胞活力中观察到IC 50大于100 mg/ml。此外，高机械性能（压力接近100 N）、多尺寸制备（d类似于4.25 cm-10.25 cm或更大）和长时间自浮（超过720小时）共同发挥优势，实现了性能优异的蒸发器。因此，本研究为高性能SGIE的设计提供了一种新的途径，即通过发挥边缘区效应，控制水流的输送，利用可持续的海洋资源进行制造。
Recently, solar-driven gas-liquid interfacial evaporation has mainly concentrated on the improvement of sunlight absorption efficiency while neglecting the regulation of water transportation. The blind pursuit of superwetting material design has ignored using excessive water transport instead to add unnecessary heat loss. Furthermore, the material biosafety also should be focused which can avoid damage to water-source biology and humans during application. Here, we successfully designed a biosafety cuttlefish juice (CJ)-based solar absorber via rotary filling SiO2 nanoparticles (NPs) to optimize the water-transport regulation of SGIE systems, the tailored absorber can block excessive useless water, and effectively reduce heat losses. Hence the absorber has specific and significant advantages: higher evaporation efficiency and fast evaporation response to the entire device, excellent biocompatibility and low-toxicity, IC50 more than 100 mg/ml is observed in the cell viability. In addition, high mechanical properties (pressure approximate to 100 N), multi-size preparation (d similar to 4.25 cm-10.25 cm or bigger), and long-time self-floating (more than 720 h) yield advantages together to achieve an excellent performance evaporator. Therefore, this work provides a new avenue to the design of high performance SGIE by enchanting edge zone effect, controlling water transportation and fabricating with sustainable marine resource.
