Bioinspired superhydrophobic surfaces are mainly attributed to nano/micro textures and low surface energy materials, and have exciting potential for use in fields such as self-cleaning, water-proofing, anti-icing, anti-fouling, and so forth. However, the natural weakness of such delicate hierarchical surface structures pose great challenges to using artificial superhydrophobic surfaces under harsh mechanical conditions. Completely transforming multi-layered composite materials with good structural ability into superhydrophobic surfaces would greatly extend their durability under continuous mechanical abrasion. Endowing these composites with electrical conductivity could further expand their scope of application, especially in anti-static environments. Here we employ a facile molding process to fabricate a new type of multi-layered and multi-functional nanocomposite (MMNC), with a tensile strength up to ∼226.4 MPa, a modulus of up to ∼24.8 GPa, a surface electric conductivity of ∼1.2 S cm-1, a water contact angle of ∼155.4° and a water sliding angle of ∼2.0°. These multi-layered and multi-functional nanocomposites (MMNCs) demonstrate robust water-repellency under harsh mechanical abrasion (tested using a high tack sticky tape peel, cyclic sand paper abrasion and even file abrasion) and strong chemical corrosion (tested by using hydrochloric acid, sulfuric acid and sodium hydroxide solutions). Additionally, our MMNCs are highly resistant to water impalement (tested by turbulent water jet impact with a velocity of up to ∼29.5 m s-1 and a corresponding Weber number of ∼32 000). The robustness of the superhydrophobicity is multifaceted, and owing to the excellent structural performance and conductivity, these MMNCs could find potential uses in vehicles, containers, wind blades, infrastructures, electronics and so forth, which usually experience comprehensively harsh conditions such as rainfall, abrasion, static electricity, high loads and so forth.
