Bioinspired slippery antifouling Co-CeO2/MoS2 coatings with excellent mechanical robustness and corrosion resistance

Rubber tire mold fouling is a severe problem leading to mold surface corrosion, tire defects, and extra energy consumption. Traditional mechanical and chemical cleaning is inefficient and induces mold surface damage. Low surface energy organic coating displays antiadhesive behavior but is susceptible to wear. Here, we develop a bioinspired Co-CeO 2 /MoS 2 coating with effective mechanical robustness, corrosion resistance, and antifouling behavior by leveraging a slippery liquid-infused surface (SLIPS) strategy. The micro-nanostructure of the coating serves as mechanical stability and anticorrosion skeleton with the infused lubricant acting as a slippery antifouling surface. The variation of microstructure, mechanical strength, corrosion resistance, and antifouling behavior of the coating with individual and synergistic addition of CeO 2 and MoS 2 is systematically characterized. The slippery Co-CeO 2 /MoS 2 coating shows excellent mechanical stiffness, corrosion resistance, and antifouling performances in rubber vulcanization conditions. Graphical abstract
