Abstract：
Natural plant leaves with multiple functions, for example, spectral features, transpiration, photosynthesis, etc., have played a significant role in the ecosystem, and artificial synthesis of plant leaves with multiple functions of natural ones is still a great challenge. Herein, this work presents an aerogel-involved living leaf (AL), most similar to natural ones so far, by embedding super-hydrophobic SiO2 aerogel microparticles in polyvinyl alcohol hydrogel in the presence of hygroscopic salt and chlorophyllin copper sodium to form solid-liquid-vapor triple-state gel. The AL shows a high spectral similarity with all sampled 15 species of natural leaves and exhibits ≈4-7 times transpiration speed higher than natural leaves. More importantly, AL can achieve several times higher photosynthesis than natural leaves without the energy provided by the respiratory action of natural ones. This work demonstrates the feasibility of creating ALs with natural leaf-like triple-state gel structures and multiple functions, opening up new avenues for energy conversion, environmental engineering, and biomimetic applications.
摘要：
具有多种功能的天然植物叶子，例如，光谱特征，蒸腾作用,光合作用,等。,在生态系统中发挥了重要作用，人工合成具有多种天然功能的植物叶片仍然是一个巨大的挑战。在这里，我们提出了一种气凝胶参与的活叶(AL)，到目前为止，最类似于自然的，通过在吸湿性盐和叶绿素铜钠存在下将超疏水SiO2气凝胶微粒嵌入聚乙烯醇水凝胶中，形成固-液-蒸气三态凝胶。AL与所有采样的15种天然叶片具有很高的光谱相似性，蒸腾速度比天然叶片高4-7倍。更重要的是,AL可以实现比天然叶子高几倍的光合作用，而没有天然叶子的呼吸作用提供的能量。这项工作证明了创建具有天然叶状三态凝胶结构和多种功能的AL的可行性，开辟了能源转换的新途径，环境工程,和仿生应用。本文受版权保护。保留所有权利。
