A durable superhydrophobic polyphenylene sulfide composite coating with high corrosion resistance and good self-cleaning ability

In this work, a durable polyphenylene sulfide (PPS) composite superhydrophobic coating was prepared using a simple spraying method. By adding GO-ZrO2 composite particles to build micro/nanostructures on the surface of the coating, combined with the low surface energy of stearic acid, a GO-ZrO2/PPS composite superhydrophobic coating with high water contact angle of 153° ± 1° and low sliding angle of 4° ± 1° was finally obtained. The coating exhibits good stability and maintains a clean surface even after repeatedly pulling in muddy water for 100 times. In addition, the coating has good wear and corrosion resistance with a corrosion rate of 3.07 × 10−8 g/m2h. Therefore, this superhydrophobic composite coating with durability, wear resistance, and corrosion resistance can provide promising applications in the field of anti-corrosion.
