through chemical deposition and sol–gel on Q235 steel. After modification with FAS‐17, the
water, glycerol, and cooking oil contact angles of CuO/TiO2 coating surpass 150° the
corresponding sliding angles are all less 10°. Furthermore, the as‐prepared
superamphiphobic surfaces can survive 500 times, 400 cm abrasion distance under 2.2 kPa
pressure without losing superhydrophobicity. In addition, outstanding corrosion resistance …
