A robust, superamphiphobic fabric with a novel self‐healing ability to autorepair from chemical damage is prepared by a two‐step wet‐chemistry coating technique using an easily available material system consisting of poly(vinylidene fluoride‐ co ‐hexafluoropropylene), fluoroalkyl silane, and modified silica nanoparticles. The coated fabrics can withstand at least 600 cycles of standard laundry and 8000 cycles of abrasion without apparently changing the superamphiphobicity. The coating is also very stable to strong acid/base, ozone, and boiling treatments. After being damaged chemically, the coating can restore its super liquid‐repellent properties by a short‐time heating treatment or room temperature ageing. This simple but novel and effective coating system may be useful for the development of robust protective clothing for various applications.
