Man‐made superhydrophobic membranes are of interest for various applications in energy, environment, and medical fields. However, simultaneously achieving durable superhydrophobicity, robust waterproofness, and high breathability of the membranes is still challenging. Herein, an efficient and powerful strategy is reported to create superhydrophobic membranes with perdurable liquid repellency and robust breathability via combining humidity‐induced electrospinning with coat‐crosslinking technology. The micro/nano rough structure is in situ constructed based on manipulating the phase separation of electrospun jets; meanwhile, the waterborne acrylic resins are bridged to the surface of nanofiber to endow the membranes with stable low surface energy via coating and crosslinking treatment. Eventually, the resultant membranes present superhydrophobicity with a water contact angle of ≈154°, good self‐cleaning and anti‐icing properties, robust waterproofness of 83.4 kPa, and high breathability of 3.71 kg m−2 d−1. More interestingly, the nanomaterials can maintain durable superhydrophobicity even after exposure to various severe conditions. The successful creation of high‐performance superhydrophobic membranes opens a new avenue for synthesizing advanced functional materials for application in a variety of fields. [ABSTRACT FROM AUTHOR]
