荷叶排斥水的能力在许多应用中是期望的，例如自清洁表面、生物医学装置和海军船只。创造模仿荷叶的层次结构和表面化学的材料需要多步骤的过程，这对于非金属产品的大规模生产是不切实际的。超疏水表面已经使用石墨烯产生。然而，通过石墨剥离或沉积在基底上获得的石墨烯片不是超疏水的，并且需要额外的工艺来实现莲花状防水性。在这项工作中，我们表明，在气相中产生的石墨烯是固有的超疏水性。气相合成的石墨烯（GSG）和荷叶具有根本不同的结构，但两种材料上的水滴表现出相当的接触角，滚降角和弹跳特性。此外，亲水性表面在被GSG覆盖时变得超疏水。GSG的无基质合成是直接和可持续的，这可以使各种防水技术的制造成为可能。
The ability of lotus leaves to repel water is desired in numerous applications, such as self-cleaning surfaces, biomedical devices, and naval vessels. Creating materials that mimic the hierarchical structure and surface chemistry of lotus leaves requires multistep processes that are impractical for the mass production of nonwettable products. Superhydrophobic surfaces have been created using graphene. However, graphene sheets obtained through graphite exfoliation or deposition on substrates are not superhydrophobic and require additional processes to achieve lotus-like water repellency. In this work, we show that graphene produced in the gas phase is inherently superhydrophobic. Gas-phase-synthesized graphene (GSG) and lotus leaves have fundamentally different structures, yet water droplets on both materials exhibit comparable contact angles, roll-off angles, and bouncing characteristics. Furthermore, hydrophilic surfaces become superhydrophobic when covered with GSG. The substrate-free synthesis of GSG is straightforward and sustainable, which could enable the manufacturing of a diverse range of water-repellent technologies.
