摘要
Abstract Superhydrophobic materials are attractive for industrial development but plagued by poor mechanical stability. Herein, we have designed and fabricated a superdurable full‐life superhydrophobic composite block by embedding near‐zero contractive superhydrophobic silica aerogel into a rigid iron‐nickel foam structured similarly to a regular dodecahedron. The synergistic protection afforded by these materials ensures superrobust mechanical stability for our composite block, which features a high compressive strength of up to ∼7.4 MPa, and ultralow Taber abrasion of down to ∼0.567 mm after withstanding 50,000 cycles, and highly efficient water harvesting capability of up to ∼3,114.3 mg min −1 cm −2 at a supercooling degree of 40 K. This robust material system provides a novel strategy to design superhydrophobic materials capable of withstanding extreme conditions, including high temperature, humidity, pressure, and abrasion.
