Robust superhydrophobic foam is fabricated by combining an ordered graphdiyne‐based hierarchical structure with a low‐surface‐energy coating. This foam shows not only superhydrophobicity both in air (≈160.1°) and in oil (≈171.0°), but also high resistance toward abrasion cycles. Owing to its 3D porous structures and numerous superhydrophobic surfaces, it can easily separate oil from water with high efficiency and good recyclability.
