The ability of lotus leaves to repel water is desired in numerousapplications, such as self-cleaning surfaces, biomedical devices, and naval vessels.Creating materials that mimic the hierarchical structure and surface chemistry of lotusleaves requires multistep processes that are impractical for the mass production ofnonwettable products. Superhydrophobic surfaces have been created using graphene.However, graphene sheets obtained through graphite exfoliation or deposition onsubstrates are not superhydrophobic and require additional processes to achieve lotus-like water repellency. In this work, we show that graphene produced in the gas phaseis inherently superhydrophobic. Gas-phase-synthesized graphene (GSG) and lotusleaves have fundamentally different structures, yet water droplets on both materialsexhibit comparable contact angles, roll-offangles, and bouncing characteristics. Furthermore, hydrophilic surfaces becomesuperhydrophobic when covered with GSG. The substrate-free synthesis of GSG is straightforward and sustainable, whichcould enable the manufacturing of a diverse range of water-repellent technologies
