摘　　要：超疏水表面表现出具有大于150°的接触角(CA)和小于10°的滚动角(SA),可在动态冲击条件下阻止水渗入其结构,因而可用于自清洁和防腐蚀等高端领域。以自然物体如荷叶和玫瑰花瓣为人造超疏水表面的原型,自清洁超疏水表面的主要问题是易受到机械不稳定性的影响,在磨损/刮擦后可能会丧失超疏水性。纳米技术的发展为超疏水表面的制备和性能带来了诸多优势,许多研究团队已经报道了石墨烯和石墨烯衍生物展现出超疏水性,因此结合这种杰出的二维材料可以制备出具有优异的机械耐久性、自清洁和耐腐蚀性能的超疏水表面。着重于介绍超疏水石墨烯基材料的制备策略和相关性能,预计超疏水与石墨烯基材料的结合将为许多高性能装备带来新的机遇。Superhydrophobic surfaces have a contact angle(CA) greater than 150° and a sliding angle(SA) smaller than 10°, which can prevent water from penetrating into the structure under dynamic impacts, and thus can be used in high-end fields such as self-cleaning and anti-corrosion. Natural objects such as lotus leaves and rose petals were taken as the prototypes of artificial superhydrophobic surfaces. The main problem of self-cleaning superhydrophobic surfaces is that they are susceptible to mechanical instability and may lose superhydrophobicity after wear/scratch. However, the development of nanotechnology has brought many advantages to the preparation and performances of superhydrophobic surfaces. Many scientific groups have reported that graphene and its derivatives exhibited superhydrophobic properties. Therefore, with the help of this outstanding two-dimensional material, superhydrophobic surfaces with excellent mechanical durability, self-cleaning performance and corrosion resistance can be generated. This work focused on introducing the preparation strategies and corresponding properties of superhydrophobic graphene-based materials. It was also anticipated that the incorporation of superhydrophobic and graphene-based materials would bring new opportunities for the development of many high-performance equipment.
