| Abstract: | Most superhydrophobic surfaces are fragile and even lose their functions under harsh conditions especially in outdoor applications. In this study, we have demonstrated a facile strategy for fabricating eco‐friendly and mechanical durable superhydrophobic material from eggshell. The as‐prepared superhydrophobic materials possess not only excellent self‐cleaning property and under oil superhydrophobicity, but also high‐efficient oil/water separation capability. More importantly, the obtained materials show outstanding and mechanical durable water repellency, which can maintain superhydrophobicity after 360 cm abrasion length of sandpaper. In addition, the materials also show durable superhydrophobic toward strong acidic/alkali solutions, UV irradiation, and water droplet impact, which demonstrates the outstanding chemical and environmental stability. This facile fabrication of the mechanical durable superhydrophobic materials and the utilization of daily garbage will provide the new ideas for engineering materials and accelerate the real application of the super‐repellent materials. |
